Yes as there will be times where you may have to do relatively mindless things that can well be part of the job. Would filling out a time sheet be something beneath you? In the real world, sometimes people may have to do work that may be thankless and not considered that valuable.

If your manager is OK with it and has updated the timelines so that you aren't expected to do two things at once, I'm not sure I see where this is disrespectful. Sometimes you may have to take one for the team.
