Reusing meeting details for subsequent meetings

Quick summary of my question: I want to reuse the meeting/chat details for one meeting in a subsequent follow up meeting without knowing in advance when the second meeting will be called.

The long version: I work with small projects and will often have a a series of events with an unknown number of days between them and the possibility that i may need additional people added for follow on events.

It's for software development, so we will develop then have a test release, fix things then have a subsequent release etc

For the sake of ease of illustration, especially for anyone who does not live and breath software development, I'm going to use a series of meals in a day to show what I want to do.

Currently we have a main discussion thread and then each meal/event has it's own meeting/chat thread. Follow on discussions get lost and can go into any of the previous chats.

I would like to reuse the meeting invite and the accompanying chat for the entire series. I appreciate that some users may be added part way through and I cannot think of a use case when I would not want them to see the previous discussions, in fact it would save a lot of time if they could.

I know that teams can't do this out of the box, but has anyone got a decent workflow that works for this?

I did see a suggestion of setting up a series of recurring meetings and then updating the dates for each, but some of the typically 20 or so people on the invite list are senior managers and it's rude to fill up their inboxes with superfluous meetings.

There's a lot of queries online from people wanting this kind of thing so I'm hoping someone has it figured out.
