Flight Question Towing modules

[Nistenf]

Hello. I'm building a little station using the Mir2 modules by kulch. So I put in orbit the Tranzit tug (a vessel that's made to be used to bring modules to the station), and a Solaris module. So I went and docked the Tranzit to the Solaris and then the problem arose. It's really difficult to rotate the Tranzit with such a big module docked to it, the prograde, normal, etc autopilots take a looong time to stabilize the vessel. So my question is, is there a more efficient way to bring modules to the station?

Thanks!
