I'm trying to make a custom field optional on some campaigns, but required on others.
Because it's a dropdown to select campaign on a custom field, I can only pick one campaign or all campaigns for a field. Similarly, I can only make a given custom field required or optional. I'd like to not have to create a custom field that's essentially the same thing for every single campaign on our site. Is there a way to do it with just one set to required and another set to optional, or do I have to make six different identical fields - one for each campaign on our site?
