How can I add multiple other options to a subsequent array question using array filters?

I have two multiple choice questions and want to populate a third array question with the multiple choice answers including any provided other options. Since the identifier "other" is predefined I don't know how to adress more than one other option, unfortunately.

I played around with a third hidden multiple choice question to collect all other-values and assigned their status with an equation. Ultimately, I listed the hidden multiple choice question as array filter. It worked, but since all questions have to be on the same page I experienced data loss on back/forward navigation.

I am working on LS v. 3.22.25 and as usual would be grateful for any ideas!

Don't try to use array filter; do it by subquestion relevance.
