Save paste stack and show picture in paste steck

When I create a paste stack, I can only use it once. Sometimes, however, I want to use the same paste stack multiple times, so I need a feature that allows me to save the paste stack and reuse it when needed.
Also, the paste stack cannot show what the picture looks like, so when I paste a picture from the stack, I do not know what I am pasting. Could you add a feature that shows the picture in the stack?
