There may be a miscommunication due to terminology errors.
With GX, there are 2 Generators - labeled "G1" and "G2". Each of these has an "Out 1" and "Out 2". For each G, the Outs work together with the boost for best contact use. Yes, each G in the GX is independently controlled, so laser can be used on Out 1 of G1 while contact is used on G2, however you choose to connect it.
