CSV / JSON / Mass-Import of date overrides

We have a lot of independend guides perform our services. Those give us appointments that we might offer our customers - or not, depending on stock and demand. We use external shiftplanning to plan this process. We cannot use Appointo Teams for this, as it's too complicated for guides to use and we'd loose control about when and where to add new appointments. A very simple solution for this, would to allow a CSV-Import or sth simliar, to add a lot of date overrides for one or multiple apppointments. The most simple way too achieve this would be adding an import to the override-modal. even better would be a bulk-edit for appointments, that allows multiple date overrides. This feature would save us dozens to hundreds of hours of work, so we'd even pay for the development if it's any help.
