Dear Bogdan,

Sorry for the late response.

We have two employees, but only one Brick and one chair.

For each of them, only some treatments can be done, and we wish the calender to be able to utilize this logic.

For example, if a wellness massage is chosen, then no other treatments can be selected which requires the brick, but for all treatments which can be done on the chair, the services should be available.
