The “Paste Recent” command is even better than macro, because it can use Shortcut to select which item for paste.
But it can not set hotkey directly, after study, I got workaround solution:
1. Use Customize Menus, specify “Paste Recent” command in “User Menu (2)”.
2. Set hotkey for “User Menu (2)”.

Hope it can set hotkey for “Paste Recent” command in the future.
