Glad I decided to ask for help.

program:
	str_in_list('Baen, Daw, Orbit, Tom Doherty Associates', ',', $publisher, $publisher, '')

EDIT: You could do it without a custom column by using the "Collections Template" option in the Kobo driver. Depending on your "rules" the template above could work.

Thank you! I think the Collections template could be perfect, if I can use it on top of the other collections columns I already use?

If it's easiest, I could use the publisher name for the collection and change the books I have marked manually, but I would like to keep the collections I already was using if I can.

One publisher name is "BEL Editions" and the collection name is "BEL", and another one is "Bibebook" and the collection is "dp". Would the template look like this?

program:
	str_in_list('BEL Editions, Bibebook', ',', $BEL, $dp, '')

Or do I need to make one rule per collection?

program:
	str_in_list('BEL Editions', ',', $BEL, '')
        str_in_list('Bibebook', ',', $dp, '')
