Can SLA bind to another date field instead of created time?

Can SLA bind to another date field instead of created time?

I insert an additional date/time field in the request called "Fault reported time" and will like SLA to bind to this new date field, instead of request created date. Is this possible?

Cause I may not be able to create the request on the spot when fault is reported. And my SLA is bound to fault reported, not request created.

Thanks.
