Opening a zoom meeting and adding an alternate to open the meeting.

We are a small group who uses zoom to have meetings. I usually schedule the meetings but I can't be always available. We have a plan that is paid for up to 100 people. It is a Zoom One Pro account. Is there a work around to have someone else be present for the meeting that does not cost? We are a small quilt guild. I leave the room open so people join when the meeting starts but sometimes I am not available.
