Client Zoom Meetings

We have run across an issue with our meetings.
Ours are setup to needing let in the meeting.

What is the best way to not have to re-setup a new meeting when this happens?
Is it possible to share a common login for regular client meetings?
Trying to avoid the last minute changes.
