To clarify, it looks like I have a black and grey tank on each outlet, so if I use the ‘Y’ I could run both at the same time (both black, then both grey)?
Realistically you can only dump one at a time.
There is no need to ever dump simultaneously. With that in mind I just move the hose. No need to get out a wye and set all that stuff up.
In my case the only tank that I need to worry about is the grey water tank that the shower goes to. All the other tanks will last the entire trip.
I attach my sewer hose there until it's time to leave.
Then I move it to the rear connection for the galley and rear bath which are never full.
YMMV
