Change Index of an InstanceObject

Hi ,

I there a way to give a InstanceObject (InstanceRefrences) a Index.
I tried the following but it works only for Name not for Index and I dont understand the Error

Thanks for any tip.

Hi @flokart,

No. Why do you need to do this?

Hi dale,

thanks for clarify.
The Idea was to select all InstanceReferences and use the slection order to create enumerated index for these objects so that i can keep the order.
