How can I use MAX endstop as home position in H-Bot ?

How can I use MAX endstop as home position in H-Bot ?
Today I revisited this issue, tried to solve it but still no solution.

I have Y endstop at top-left corner, where I want to be MAX. I could only enable max endstops and confirmed triggering.
But printer doesn’t move to home position, when I changed homing direction in Marlin. Inverting motor direction(both) would result X homing instead.
I’m stucked here
Any help would be great.

I don’t think marlin can support homing to MAX endstops for coreXY or H-bot systems yet…some day hopefully
Your other option is to home to MIN, but your y-axis will be inverted
