Copy parts from multiple layers into multiple layers
I work with a lot of parts that I need to keep separated for output. A simple example is a complex, compound shape with 20 elements. I have 10 on a "cut" layer and 10 on a "print" layer. If I copy and paste them, I can only paste them into one layer. I might want them to go back into the same layers or into 2 new layers. I never want them in the same layer. I now have to go in and separate them all into the proper layers.
This is important because the layers tell our output machines what to do with the files.

You can enable Paste Remembers Layers in the panel’s menu to make Illustrator remember layers your objects were copied from and insert them on layers with same name when pasted. If these layers don’t exist, Illustrator will create them. Be careful and disable it when not needed, if might make a mess when not needed. Also note that with this option enable everything copied from an isolation mode creates a separate 'Isolation mode' layer, which is stupid — vote here if you think this should be addressed: https://illustrator.uservoice.com/forums/601447-illustrator-desktop-bugs/suggestions/37935496-paste-remembers-layers-bug-with-isolation-mode
Check 'Paste remembers layers' in 'Layers' palette options. Use search in Internet too :)
Does it work for you in this way or not?
