How can I tell if my BPSORT waits are the result of spilling batch mode sorts?

BPSORT sort waits mean that I have batch mode sorts . This is okay. However, I'm aware that batch mode sort spills are very slow . How can I tell if a query that appears to have high BPSORT waits is suffering from batch mode sort spills? Assume that I am on a live production server. This makes both Extended Events and getting actual execution plans awkward. Other tools, such as the plan cache and Query Store, are available.
