As a professor, my understanding is that professors used to have assistants for these sorts of things in the distant past, but this is much less so nowadays besides deans or higher ups. People only in leadership positions seem to be able to get them when in a university setting. This isn't true everywhere, e.g., my academic medical collaborators typically have assistants and so do the lab heads associated with non-profit research organizations (e.g., Salk). Department heads may have them, but even that seems to be happening less and less. Unfortunately, professors currently have to spend a lot of time doing tedious administrative/organizational work unrelated to research/teaching.
