I cannot seem to find this button listed in any help file. Never seen it before but it seems to do what I want better than Add does.

This button adds a related point visit and properly inherits both of my related fields.

When I go to Related then Add it only ever inherits one of the fields. And strangely it inherits the same field on both RCs.

So it does work better but I need to figure out why.
For now I have been adding two relationships class - one for each field. I would rather just have one as the users are confused - but would this still work? What is the proper method to inherit multiple fields?
Thanks for any help!
