Custom Hours for a subscription type

This is something we thought appointo could already do. We have one large shared calendar of 15 pottery wheels in a studio that can be booked at either 10am, 130pm, or 5pm each day. we are selling a "lite" membership that would restrict those who are not using our studio during the busy evening hours to only booking during the daytime. we would love to have the same connected variant but a subscription type would only be able to book during 10am and 130pm. never during 5pm or on a weekend.
