Enable an option to re-accept declined meetings that are part of a series.
Add an option to be able to accept individual meetings which are part of a larger series after the individual meeting has been previously declined. It is possible to find a deleted invite for an individual meeting and re-accept it, but there seems to be no way to re-accept a declined meeting which is part of a series.
Similarly, enable the option to re-accept a declined series--that's currently not possible either. (This seems close enough to be worth adding it to the request here, instead of starting a new one.)
