Planning with surface transfer

Hi, I have a following question.
I fly from DFW with fixed hub times, and want to start some regio services from DAL. Ground time between DFW and DAL is 1:04. Does it mean, that if the fight to DAL arrives, say, at 4:56, and the flight from DFW starts at 6:00, it is enough time for the transfer? Or the min. transfer times come in play there?

Currently, ground transfers for intermediate segments are not supported for performance reasons.

Hmm, a pity ;( Then it will have to be just a second hub
