Treat clipboard like a stack

[dpmccabe]

Is there a way to use a Javascript custom command to treat the clipboard like a stack? In other words, when you press the keyboard shortcut for the command, it pastes the top item in the clipboard and removes it? This would be useful in the case where I want to copy many snippets from different places in one app and paste them individually in some other app.

I can't tell on the site's custom command documentation whether there's a way to access the app's queue in order to remove an item after pasting.
