Completing GPP on same day as regular training

I’m currently running Powerbuilding I for the second time (really enjoyable program) and was wondering if it is ok to do the GPP conditioning, arm work, upper back work, and ab work on the same days as the regularly scheduled lifting sessions as opposed to doing the GPP on separate days. As of now, I’ve been training in the evening. Would it be ok to complete all of the GPP either first thing in the morning on my training days or right after lifting in the evening on those same training days?

As much as I enjoy training, I do have other hobbies and interests outside of lifting so I’m trying to figure out ways to create time for them.

Thanks!

Totally fine. Carry on!
