global time "padding" across all booking types

I'd like to be able to have my chosen time "padding" between appointments applied across all booking types. At the moment, I can set 15 mins (for example) between appointments of the same type. But if another person books another type of appointment just after, I can end up with bookings back to back, which I want to avoid. It would be great to have this option in global settings / global availability. Thanks!
