Can I use bleach in my spa as well?

I had a lot of spa use over the weekend and the FAC was low, so I added some spa dichlor. My CYA has been creeping up for a while now, I think because I have been using Leslie's chlor-brite as my main source of sanitizer. Now the CYA is at 100+ and I need to drain some water out, not what I want to do tonight...

Q: if the CYA is fine and my water test shows chlorine low, can I simply add liquid bleach to the spa with the jets running to keep the CYA where it is? My current PH is 7.4 and TA is 60. Thx.
