Gp Shift On 2019 St Rs?

I recently got a Ninja 400 to be my first track-specific bike (although I am keeping it street legal) and have set it up with GP shifting (which I really like). When I get back on my Speed Triple, which I ride 60% of the time, I have to remind myself that it isn't set up for GP shifting. Even so, I inevitably mis-shift a few times until I get back into the groove. I asked my Triumph dealer if there was any way to change the ST to GP shift and he said "no." Is that really the case? (Sorry if I have missed a thread on this topic.) Seems odd to me that such a track worthy bike as the ST cannot be set up for GP shift.
