Lock objects in UI so that user can SELECT but not move, delete, etc

Hello,
I am wondering if there is a way to allow the user to select items, but to prevent the user from changing anything of these objects.
Basically I want to lock the objects, but still allow the user to select them.
Is there any way to do this in Rhino?
Thank you!

Let me clarify - I just want this to happen while a form of my plugin is open.
I am considering responding to the following events and “undoing” their change if the object is to be “locked”.

            RhinoDoc.DeleteRhinoObject += RhinoDoc_DeleteRhinoObject;
            RhinoDoc.ReplaceRhinoObject += RhinoDoc_ReplaceRhinoObject;
            RhinoDoc.BeforeTransformObjects += RhinoDoc_BeforeTransformObjects;
            RhinoDoc.ModifyObjectAttributes += RhinoDoc_ModifyObjectAttributes;

In the end I managed by listening to the Add and Delete events.

        private void RhinoDoc_AddRhinoObject(object sender, RhinoObjectEventArgs e)
        {
            // Automatically deletes the object
            string typeString = e.TheObject.Attributes.GetUserString("T");
            if (!string.IsNullOrEmpty(typeString))
            {
                if (typeString == SoftwareObjectType.FrameTheoretical.GetObjectTypeAbbreviation() ||
                    typeString == SoftwareObjectType.InnerJointTheoretical.GetObjectTypeAbbreviation() ||
                    typeString == SoftwareObjectType.ModelJointTheoretical.GetObjectTypeAbbreviation())
                {
                    // Should re-add the theoretical object
                    e.TheObject.Attributes.SetUserString("TAD", "1"); // Setting a flag for the delete event so that it doesn't re-add
                    StructuralLidarPluginData.Doc.Objects.Delete(e.TheObject);
                }
            }
        }
        private void RhinoDoc_DeleteRhinoObject(object sender, Rhino.DocObjects.RhinoObjectEventArgs e)
        {
            // Readds the object
            string typeString = e.TheObject.Attributes.GetUserString("T");
            if (!string.IsNullOrEmpty(typeString))
            {
                if (typeString == SoftwareObjectType.FrameTheoretical.GetObjectTypeAbbreviation() ||
                    typeString == SoftwareObjectType.InnerJointTheoretical.GetObjectTypeAbbreviation() ||
                    typeString == SoftwareObjectType.ModelJointTheoretical.GetObjectTypeAbbreviation())
                {
                    // Re-adds only if it is not the theoretical object being auto-deleted 
                    if (e.TheObject.Attributes.GetUserString("TAD") != "1") StructuralLidarPluginData.Doc.Objects.Undelete(e.TheObject);

                }
            }
        }

To answer your question, no, there is not.

That would be a great addition.
