You can streamline things by creating a button which runs this:
@nodeselect
Rename ADVANCED PRESET=findrep
Then just click it again to do another find & replace on the same set of files.
The only real annoyance is that it opens with focus on the new name so you have to click or Shift-Tab back to the old name field.
Another way to do it, which is more technical to setup, is with a rename script which does multiple find & replaces in one go. (Script to perform multiple Regular Expressions would make a good starting point as it does almost that already.)
