You mean besides schlitz and giggles, just to see if it can be done? I use the "thumb slider" right now for the second throttle on my 110. It' perfectly usable, but I notice that if I don't zoom in on the manifold gauge, and make sure both needles are perfectly aligned, I will drift in whichever direction the stronger engine is taking me. So, I thought maybe another full throttle would be easier, and then I'd have two sliders for engines 3 and 4 in a bomber, if I chose to do that. dual throttles is "da bomb", so to speak, because SO many MA pilots automatically think that a 110 can't turn or stall fight....pfffffffffffffffffff ffffffffffT!
