It is supposed to remember the last charge rate at that location(or is it that particular charger, I can never remember which).
Note there seems to be two ways to interpret your question:
If you don't unplug the car from the charger for those few days, I'm pretty sure the rate will be remembered.
If you do unplug the car and go for a drive and replug, its supposed to remember, but is not super reliable. After a car reset or new firmware loaded into the car, you might find it starts charging at 32A again. If you know you don't (and won't) have the capacity for a 32A continuous draw, get a 14-30 outlet installed and avoid having to set it every time. Alternatively, get an HPWC and set it as if it has a 30A breaker. Another super-sleazy solution is to get a 14-50 to 14-30 adapter and then use the 14-30 adapter for the UMC.
