[Appointments+] Exception Hours

Hello, I request the following feature for appointments+: Presently it is just possible to open or close full days in the "exceptions" fan. It should be possible to make exception HOURS. Presently it's not possible to do this unless changing absolutely all hours that day, which is a big pain when one needs to do smaller changes, or compensate for lost time spread out on several days. Thanks in advance, i'll wait an answer !!
