Posting for a customer.
The use case is that they are wanting to use a CTA field in a rule additional field to assign a default a value but the only way to accomplish this is to make the field editable.
The issue is that if the field is editable then the CSM or end user is able to change the default value.
A workaround is: You are able to change the field back to un-editable to resolve the issue if the rule is only fired once, but for a scheduled rule this does not work.
Is it possible to allow the fields to be added in the rule and set a default value, but not be editable where the end user can change the value?
