Is it possible to add button on "done tasks" menu, so that i can start new process from done tasks

Hi, please let me know how to achieve this.

i have a simple flow where document is approved.after approval, workflow will end.

but need to implement something like- from Done tasks, select one case - select the approved document and set new data variables then start same process again(add new button here to start process).

so the Approved document should also be uploaded to new process along with user form input(default data entry).

thank you.
