Changing my Availability Preferences?

Hi!

Is there a way to list space for one dog only, but across both day care and dog boarding? My profile is currently set to have space for one dog for boarding and one dog for day care. I can't find a way to change it so that if I only have one dog at a time, rather than one dog per service. Is it possible to set availability that way, or would I just have to manually decline requests if I already have the other service booked?
