Refer to the definition of clocks, define the value of maxItems slightly larger (3),
and reserve a little expandable space without affecting other definitions.
If you need to configure 3 resets in the future, you only need to define it
in individual schemas, and you don't need to adjust this item anymore.
I will adjust maxItems to 2 in the next version.
