Excluding %field% from an "_ALL" action

Hi i am trying to figure out if there is a way to create an "_ALL" action while i exclude Filename an Directory from being touched.

For example i want to remove extra spaces from all the fields, but not from filename or Directory (connection with some programs will be lost if these fields will be changed making these files "missing".

see e.g. here:

OK so it seems that choosing _TAG does the trick...
I wonder how this slipped from my eyes...
Thanks @ohrenkino
