Pretty straightforward request:
Right now, attachments in Field Maps are named simply "Attachment 1", "Atttachment 2". This is fine except for when you go to export them and suddenly you have 50 "Attachment 1"s.
What I'd like to see is the option of naming Attachments using a field (or combinations of fields) and Arcade Expressions.
For example,
{Field1}_{Field2}_Attachment1 OR
"Site_" + $feature.SITE_NO + "_Feature_" + $feature.FEAT_NO + $attachmentName
//Forgive me, I don't remember how to deal with Attachments in Arcade
//so I'm just making it up lol
Survey123 has this option already: Survey123 Tricks of the Trade: Set the file name of photos and signatures (esri.com)
It'd be great to have it in FieldMaps as well.
