There was a generic seat map for advance seat assignments that included all of the seats common to all three versions, but when the ship number was actually assigned to the flight (usually somewhere 4-12 hours out), the seat map would change to reflect the actual F configuration.
Many a time I was in a less desirable seat, or was split up from a traveling companion, but I would be able to grab 6A/6B (or 7A/7B) when the seat map updated once a ship number was assigned.
So, from personal experience, I know that Deltamatic can handle this function. Perhaps that function has been removed now that IT is being tinkered with, but historically it was something that was done.
But those 752s all had different designations (752, 75E, 75X, etc), I'm guessing, whereas the 319s are all the same. If DL were to take the time to re-designate one version of the 319, they'd be able to do it, but I'm guessing in their view, it's not worth the effort, meaning DLMatic won't be able to handle it.
