Is your feature request related to a problem? Please describe.
Usually when I use move patch into new commit I'd like to reword that commit, I'd rather get the popup with the Split from <patch message here"> as initial value than having to manually go back, reword the newly added commit, and return to the view where I was (since I want to split a few other things as well)

Describe the solution you'd like
Popup for the new commit message.
