How can I request for more groups to be created?

You can request for a group to be created here:
As we are receiving a high volume of group creation requests from the community on a daily basis, it may take a while before our team gets to your request. That said, groups that are requested for by more users stand a higher chance of being created! Thus, if you really want your requested group to be created, you can ask your friends or other like-minded Carousellers to request for this group too.

Do also keep a lookout as we are continuing to create more new groups every day :)
