Block certain booking types on specific dates.

Hi all, 

Looking for a way to block certain bookings on specific dates. I work hybrid, and some of my bookings require me to be on-site, whereas others are virtual meeting bookings. I have my regular hybrid schedule set in the custom availability section for the on-site bookings, but when I am travelling or have specific dates that differ from my regular hybrid schedule, I want to be able to turn off bookings for the in-person meeting type. The only advice I've seen is to block the time off on my outlook calendar, but that then blocks folks from booking virtual meetings and makes my calendar inaccurate for internal folks looking at my calendar. 

Is this just a feature that Microsoft doesn't have? If not, what can be done to get that feature added?
