How to paste on all (or multiple selected) layers Adobe Illustrator?

[TTOWN71]

I'm at the end of creating a typeface and would like to paste repeating Diacritics (accent characters) in the same spot, but on all the layers in my document instead of pasting in place one by one. I don't mean "Paste remembers layers"

I've searched the net, but have not found anything. Any ideas?

Much appreciated.
