Create Groups within Flows
You should be able to add groups from a flow page. I find myself adding a new action to add someone to a group, but it is for a group I haven't yet created. Being able to add it straight from that dialog would be very convenient.
You can now type the name of a new group right from your flow to create it as you go.

I wish to put in the condition that if person triggers the flow before 5th December, he should fall under Group 1 otherwise who registers after 5th Dec should fall under Group 2. I have programmed it based on the Program Enrollment Date of a user. the day when the person enrolls, his program enrollment field is updated. Then I chose "Split on Program Enrollment Date". On selecting "has a date before", it has "today + x days", What value does today take?
If I consider "today" to be the date when I created the flow, the flow is not working as desired. It is not grouping my contacts who trigger the flow.
