Do you need to do anything to change a date for a recurring walking?

I set up my first dog walking job on Rover last week. It is set up as a M/W walking, but the dog mom is very flexible with whatever days is best for both our schedules to have her dogs walked. If I have to switch a day do I need to do anything on Rover differently? Can I still send a Rover card for a Tuesday if I couldnt walk them on a Monday?
