Is it possible to set 2 passwords for one meeting?

I sometimes host guided meditations meetings for members of my group and would like to be able to set 2 different passwords for the same meeting. The reason for this is that we have paying members that join using one password, which stays the same for each meeting. However, we would like to offer occasional access to the same guided meditation meeting to non-paying members as a trial for whom we'd like to have a different password (both to track who joins under that password and to ensure that they don't have access to the meditation group meeting all the time). I'm not sure if I explained that properly. As I understand it, this is not possible at this time but it would be great if it could be in the future.
