I need a software that can edit clipboard to sequentially use the copied texts

I need a software that can sequentially use the copied texts on the clipboard.

Like this: I put 15 certain texts on the clipboard and then I want to use the first one eight times, then after I pasted it eight times, it will then switch to the next one, and so on.

Actually I use macro, after the macro used Ctrl+V eight times, i need the clipboard to automatically switch to the next text.
