One task per line. Separate the fields with | or a tab (so you can paste
straight out of a spreadsheet): Task name | meter interval | months | category
Meter and months are optional individually, but a task needs at least one of them or it
can never come due. Category defaults to General.
Example: Change engine oil & filter | 250 | 12 | Fluids
Duplicate Schedule
The copy starts with no equipment assigned, so it will cover every active unit of the type
you pick. Assign specific units afterwards if you want to narrow it.
