I don't think it is possible; but, I wanted to throw it out there if someone has an idea or could enlighten me :)
I want to have a sublist call a saved search from a Case Record. This saved search contains transaction records. Both the Case and the Transaction have a custom record in the middle which they are both related to but.....the relationship (field id) is different because one side is a transaction and one side is CRM. Anyone think it is possible to show transactions on the case with this pattern?
