Are we able to do Multiple appointments?

Informational question: Is there a way to setup up multiple (but nor recurring appointments? Or is it manual entry (one at a time)?

I'd like to setup 3 appts: the first 3 weeks out, the next 2 weeks later and then a final 1 one week after that. Is there a way to do that or do I need to go through the Appointment page once for each date?

Thanks in advance,
