after I have mastered the notoriously tricky "subfolder"-question, I have run into something unexpected:
I have two rule-sets working on same folder + its contents. that is because I want to add information to a subfolders content-files, while retaining all the info from (the rules of) its parent-folder/s.
now: I can´t find a way to append spotlight commentary info. everytime a rule runs (originating from either parent-folder or specific subfolder) the prior, existing spotlight commentary content is *completely replaced*

it works fine with tags, where actions *combine*. I can´t really believe there is no way in Hazel to add-up the content of the commentary-field...
– but I am only finding one option under "Do the following...": and that is *add* comment. there seems no way of determining whether it´s *replace or add*. and actually, I would be very happy if *add is really add*

so, ... am I overlooking something?
any help or hint appreciated! thx in advance!
