quick suggestion

One major problem I've been having with the default ground ATC is when you have two parallel runways, with the outer one for landings and the inner one for take-off. As the planes land on the outer one, they try to get to the terminal, which means they have to cross the inner runway. But if there's a take-off que, they never get clearance to cross the runway, and the traffic gets backed up. I would think that IRL the tower would halt departing traffic for all of thirty seconds for planes to taxi across.Is there any way that this can currently improved? Is there any ground control utility that's like what AI smooth does to approach traffic?Since the upcoming v5 is going to feature ground control, I think this would be a good thing to fix.thanks.
