Meeting Registration

[Aloha]

I have a series of 8 weekly meetings set with required registration which I thought would cover all 8 sessions with a one time registration but when the registration populated on Zoom it set up registration for all 8 sessions separately. What should I do if participants accidentally registered for only the first session or first couple of sessions but wanted to attend all sessions ?

If they are not registered for subsequent meetings will they be able to get into the subsequent meetings with the initial meeting link ?
