Separate shortcuts for Paste Stack

Paste Stack is one of my favorite features, but sometimes I discover I need to briefly pause my work and copy/paste something before resuming the work with the stack, or maybe I mis-pasted something from the stack and need to do it again, and everything derails pretty badly. So my request would be to have an option to treat the Paste Stack as a separate entity. Instead of a single "Activate Paste Stack" shortcut that then overrides normal paste operations, it should have two shortcuts: "Copy to Paste Stack" and "Paste from Paste Stack". With this setting enabled, ⌘C and ⌘V wouldn't change behavior when the Paste Stack is active; the user would instead have to explicitly use the designated shortcuts.
