This is probably a weird question. I want to have some nodes to keep track of multiple Objects and an unspecified number of attrs, and then have all of the available in the node editor. I thought the best way would be to have a multAttr where I could feed each element a list of the actual object and the names of the needed attrs. Is there a way to do something like that with simple addAttr commands?
I probably need to start learning how to build my own nodes... :)
