Is there a way to attach a user event & client script to an address form?

client yes, user event no

@battk Sad! Is there a way to modify addresses when created through CSV imports? We need to mark a checkbox that it is residential or commercial when they come in.

I believe you can access the address subrecord using a UE script. Have you tried that?

I haven't. So basically when a customer or sales order is created/edited check then. That's my backup plan
