(Re-)implementing f1tr=, etc. for {{temp|head}}?

How hard would it be to do this? It seems it should be possible since underlyingly it's supported in the module code. I ask because things like {{arz-verb}} and {{arz-noun}} are written to use f1tr=.

I thought I did that already?

Well, something doesn't work. Take a look at حفظ under Egyptian Arabic. The imperfect should have a translit by it. It uses {{arz-verb}} which does fill in a translit using impftr=, and this is mapped to f1tr= by {{arz-verb}}, but nothing is displayed. Maybe you have a hack somewhere to only display translits for certain languages? If so, can this hack be extended to include Egyptian Arabic (and probably various other Arabic dialects, at least Moroccan Arabic, North Levantine Arabic, South Levantine Arabic, and Libyan Arabic)? Thanks.

I had a look, and you used the wrong number. "Perfect" was already form 1, so the next one after that is form 2.
