Set a shared default for a sync, then override it for one destination calendar. What you can vary, what you can't, and which way round it works.
Set a shared default for the whole sync, then override it for one destination calendar. This needs a Pro plan.
It lives inside Appearance, under the shared settings.
The usual case: you mirror Work and Personal, and you want the work calendar to see nothing but "Busy" while the personal calendar shows real titles. One sync, two treatments.
Anything landing in Work now reads "Busy". Anything landing in Personal keeps its real title.
An exception describes the calendar events arrive in, not the calendar they came from. You're answering "what should copies look like when they land here", not "what should this calendar send out".
People set it backwards the first time and then find the mask on the wrong side.
Everything in Appearance: title, colour, privacy, descriptions, guests, reminders, availability, location, and whether the SYNCDATE line appears on the copy.
Filters. There is one setting for each of these and it applies across the whole sync:
So "Work gets only my accepted meetings, Personal gets everything" isn't achievable with an exception. Build two one-way syncs pointed at each other and give each its own filters.
Colour is the one setting that can also be decided by where an event came from rather than where it lands. Above the colour swatches, switch from One color for everyone to Match source calendar, and everything from your work calendar is one colour wherever it goes, everything from a client's is another.
Colour is the only thing the source side controls. Every other setting is decided by the calendar events land in.
