Modify Item in a list, safe and move on to the next one

Hi everybody,
I have enjoyed this Forum a lot for my first projects in Grasshopper, so thanks for sharing all that kowledge.

I now have a problem where I just don´t know what I would search for:

I have a list of Objects, generate their Center Point and then manipulate those Points with Sliders until the position is correct. I want to replace the old Vector in the list and then change to another one in that list and manipulate that one. So my Problem is how to save the changes in the List for each point individually.

So… you are trying to do some “manual one by one” work?
I think Grasshopper is not really the best tool for that… you should just do that in Rhino.

Or, internalize the points , this will detach them from its original source, and you will be able to drag around each point with the gumball. Then you construct a vector from the original centers to your dragged points, and do your stuff…

Check this:

Another idea, but seems really bad:
