When using a connection I would like a way to select all as today I have to type and select each connection for lots of records.
You have brought up a great point! This is something I'll bring up internally (to include connection fields in the bulk update option)
For now what we can do is use the "match" option when importing. Here's a video demonstrating this. https://www.screencast.com/t/ssn5uYjuU
I don't mean on import, I mean if I have a Connection Field with a One to Many and I have 10 choices (Call them Categories) then if I want to connect to all 10 today I have to type, click and select then repeat 9 more times.
It would be nice to be able to have a "Select All" option too.
