Smart recurrences currently only give available alternative room for the entire series or nothing at all and does not mix and match if for instance, 8-9 meetings in the series of your chosen room is available.

This functionality already works using the Condeco browser app, where an alternative room can be added with your room of choice, and one or instance in the series isn't available.

Instead, the app should provide an alternative room to fill the gap for the 1 instance in the series that your chosen room cannot be met. e.g. 8 meeting in room A and 1 meeting in room D
