I want to see, per month, how many users that did a session signed up in this month, and how many signed up in previous months.
I can do a breakdown of registration month (user created), but that does not cut the group into these 2 specific dimensions:
What I want is:
June: 15% users that signed up in June, 85% users signed up before June
May: 25% user signed up in May, 75% user signed up before May
I can make a custom group for each month but that would not allow me to show it all in 1 overview month of month. Is there a way I can make custom dimension that says: If month of event (in this case session) is same as user creation = Yes, if not the same = No.
