Yep, or set the DI out on the amp to pre, if possibly - same thing as using a separate DI box.
I do just that - use the VT's control to do the basic sound shaping, so it sounds good in the PA, then use the amp's controls to adjust my stage sound. Works out pretty well, and I can fiddle with the knobs on my amp for the entire gig without affecting the PA. I just have to remember to not touch the VT anymore
