I get what you say!
Please note that from OFF, with Group Mode B, you have something more or less similar to what you mention but with double click + hold.
Meaning: OFF > Double Click + Hold = Turbo and starts descending in the mode sequence (T1 > H1 > H2 > M1 > L1)
In this group mode you also have the possibility to go from the lowest mode up to the top (0.5s press from OFF for Low and then click & hold to change modes - ascending -, like in an Olight). Single clicks are for ON/OFF .
The Group Mode B is “simpler” than the A one! Only thing I wish it had, instead of “Double click to SOS” was “double click to Turbo”, that can only be accessed from OFF in this group mode.
