Yes, in short pretty much like Subject works, but be able to base this on normal tables. I just want to load an array with child and parent records in several levels and select the bottom one. Main purpose is to avoid having several filtered tables dependent on each other taking up space and making the user confused. Subject can be used for this, if not already used for something else, but it's a pain to deploy since the data is stored in hidden tables that requires coding to transfer.
