hashcat -b : How do I only benchmark test for certain hashmodes?

[zun_rhmn]

Basically the title, I want to only test for wpa hashes such as mode 22000 instead of all of them. Is there a way to do that besides adding '| grep 'wpa'' ? Because that only grabs the lines with with 'wpa' and not the statistics. Might be an obvious solution I'm missing but I'm open to anything.

"-m 22000 -b" will only test 22000
