Auto forms silently drops some associations

I ran into this while trying to use auto forms, grabbing values from the created 
_join
 form. There were no errors, but not all of the resource associations were present. Looks like here https://github.com/ash-project/ash_phoenix/blob/main/lib/ash_phoenix/form/auto.ex#L469 we use 
Enum.find
, so we are only getting the first occurence of the association. I tried editing it to 
Enum.filter
and changing the type from 
:single
 to :
list
. This made the associations properly appear in the form, but submitting it failed.

Got me wondering a few things. First, maybe I screwed up somewhere before 😅 . Secondly for fixing it if it is a bug, it doesn't seem like we can know :single or :list beforehand , so would we need to use an anonymous function to resolve which similar to how data is resolved? 
type: :single,
 data: &get_join(&1, &2, relationship),

Alternatively, is it possible to just make them all 
:list
 and handle the length = 1 case for single?
