vacation, time off etc for the year, must be done individually in the availability of each event! With 10 events (products/services) and more to come that is simply too much time and hassle and will certainly lead to mistakes.

Only with integration with an external calendar this seems possible. So the external Calender will be leading ;-( It's too bad you don't have this standard feature like all the other booking software out there.

Will this be on the roadmap?
