user-editable clipboard for most needed objects

I think, it could take a corner at the edit-window (se attachment) where the mapper could place the things he at the moment needs very often.
Pe I am mapping recently hiking routes where a lot of guideposts and informations boards ar placed along. To avoid all the scrolling forth to mark the last guidepost and scroll back to where I want to duplicate it, I'd like to have a corner where I could stick these objects.
IMO such a clipboard would allow a lot of users to work faster.
