Warm up catalyst codes - Is it worth trying to change the secondary O2 sensors first?

I've had repeated warm up catalyst codes on bank 1 and now I'm starting to get it intermittently on bank 2. The warm up catalyst code is the only code I'm getting. I changed the primary O2 sensors previously because I had codes for that but those codes never came back.
Does it make sense to try to change the secondary O2 sensors to see if that clears the code or is it definietely the pre-cat going out and time to shop for new DPs.
