We have a form with settings for customers that is used for 2 types of customer, where one of those is basically a parent to the other. For a lot of fields the rule is that the setting of the parent is valid as long as the field is empty in the form of the child.
This works fine, but we would like to be able to show the value that is used for the parent in the form of the child so it is clear which settings are used for the child.
I think this basically means we would like to use an expression as the default for the childs form. That way we can show the parent's value without actually having to copy and store the value to the field on the form of the child.
