[FX.php List] Showing last related record - sort in FM or just PHP?

Probably... if you were actually going to do some form of sort, then it
would most likely be quicker to do it in php. If it was a sort order
applied to the relationship I don't think it will make any difference...

Personally I think this would be the slowest option... unstored
calculation  fields are going to be slower for the wpe to process than all
of the related records (IMHO)
