Here is what I would like to do for my parish, let's take the example of the Sunday mass at 11 am. I would like the person in charge, for example of the sacristans, to be able to easily create a schedule indicating the sacristan responsible for each week and that this information can be found in the celebration sheet. The idea would be for this manager to have access only to this schedule and not be able to access and modify the schedule of the other actors in the liturgy: reader, & co... To make it easier for him, the idea would also be that he could have his group of sacristans and easily select the group of the week without looking through the entire list of parishioners. Today the only way to do this I have found is to open each celebration and add an actor, but in this case my sacristan manager can also change the other information about the celebration, which I do not want and the action to fill in every Sunday is very tedious.
