I may be missing something, but after a quick reread of the manual, Trigless Trigs do not Trig machines (e.g. Flex, Static). The machine may let you lock a different sample in the Trigless Trig, but it will not Trig the machine, so I don’t think it would have any effect.
So I guess I have to agree with avantronica and ask what you are trying to accomplish.
