Share 'Pause & resume, with 2 dwg'

Hi Roy, is it possible, with nXt running on a dwg1, make a pause, open another dwg2, run nXt on this dwg2 (the dwg1 is open and nXt on pause), stop and close the dwg2, and resume the dwg1... ? If not possible, is it a big work for you to allow this fonction? I could do it to verify, but an important job is running since two days, and I'm afraid to loose a part of my render for this experimentatio…
