Suspend syncing while away from base?

When I am at home my main computer syncs with my secondary one every hour by direct sync.

I am away from home at the moment with the main computer, so don’t want it trying to sync every hour. The only way I can see to stop this is to change the sync schedule for each database to manually.

What I was looking for was a button to “suspend schedules” or similar (which Chronosync has, to address the same problem).

Is there a way to do this with DTTP?
