Recategorizing SD Tickets


Is it possible to allow SD ticket recategorization functionality after it has been escalated? This button exists only before the SD is opened. Sometimes, after an SD has been escalated, we need to change an Incident to a Request or vice versa. this means we need to close, then create a new SD - Escalation each time.  What is the impact of changing this? Will this cause a problem for any backend processes?

Thank you!
