Running a pack on a day it doesn't normally run

Moving a WHOLE pack to another date is a guest pack: Planner → the target day → Add guest pack → pick the source pack → set the van and driver for that date. Every dog keeps its usual pickup order and the standing weekly schedule is untouched.

A handful of named dogs joining an existing run is a guest dog instead — added one at a time from the day's exceptions.

Removing a guest pack takes every dog in it off in one go; removing a guest dog takes off just that one.
