I agree with techman01. But, if you're concerned whether or not it's ok, why not ask the scheduler? If your scheduler says yes, then you're in the clear. If they say no, then you have to decide how you're going to handle it.
I'm sure you're thinking it's easier to get admonished than get permission if you're caught. But, if you know you're in the clear, you can do the shop without second guessing the outcome if it turns out you were supposed to do it alone.
Sincerely,
H.A.R.D. at work
