Can I change how groups are listed on the GroupFinder?
Technically, no, right now the way groups are listed cannot be changed. At this time, we list groups on the GroupFinder alphabetically.
However, what you can do is deep link to your groups from your website to show specific groups by the day of the week, type of group, etc. Rather than embedding the GroupFinder on your groups page, you can add custom buttons/graphics that match how you'd like groups to be listed and link it to the GroupFinder with the filter preset to that specific day of the week.
