Add Drop down properties and Sync Properties to assign associations!

I’m unfortunately hooked up to SFDC and I need to be able to use drop-down fields to assign and unassign associations to do so many critical processes!!

Even outside of the SFDC more field options would be SO helpful! Im shocked everytime I encounter this issue. to the point I have to go to support to figure out what is wrong. It seems obvious that it would be there. please help!
