One night
The advance and the show stay separate
Tuesday is the prep. Wednesday is the show. You can see which call is still short a person, and you schedule the one who can fill that hole.
For live production
Scheduling is at your fingertips. Leave the role open until someone is in it. They answer by text, and the production manager sees the yes or no. Everyone else stays quiet.
The week, the session cues, and the crew list are the screens you actually work in. Open roles stay visible until they are filled.

Festival
The name and the venue stay put. Saturday can have its own people and its own times. Someone who is off that day is left off that day, not the whole run.
Conference
Each session carries its own cues. A breakout can run in the next room at the same time, and the load-in stays on the same call for the crew.
Tour
Add a stop and it picks up the day before it. Then the venue, the times, and the crew can change for that city alone.
