If your ZVI light source doesn't give you enough leverage either way, just use maximum "white light", which will probably be actually blue-green (since no red is needed with paper), and apply a supplemental coated glass filter over the lens, either deep blue or deep green. Yes, that amounts to "split printing";
but even that doesn't have to be all or none. You can use just a part of that practical concept to just tweak certain things if needed.
Is your "beeper" adjustable? I don't use a ZVI cold light, but a big high-output Aristo blue-green one, far more powerful than the ZVI, yet with an accessory ZVI compensating timer which beeps, and don't have any of that problem you describe.
Heck, I often print on MGWT and Cooltone during the same session, in the same developer (130). MGWT needs longer exposure time; but otherwise, no real difference in technique which isn't otherwise image-specific.
