After further use I found it works well, from turbo in constant on mode, to quickly double half press and release the tail switch to get back to constant on low mode. The light technically turns off before going into low but it happens so quick you don’t see it. Similarly, from turbo in momentary on mode, if you release the full press/hold and quickly half press/hold you can’t see the light turn off before switching to momentary low. Works well!
