Allow use of "in past before" or "in future after" for date constraints

[Travis_Schwartz]

I have challenges where I want to create a smart list with date constraints, but because it does not allow me to use "in past before" or "in future after" in the date constraint section, I have to manually adjust that every month instead of automating it.

for example, I want to create a smart list of people who filled out a form in past before 2 months. To accomplish this I have to do "or or before" and set a specific date, and every 30 days, go back and update the date. The fact that I can't say "filled out a form in past before 2 months" and have to constantly go back and update the date is silly and frustrating.

I honestly can't believe this doesn't already exist. The documentation about date field operators makes it seem like this is available on all date fields, and then I find out from support that's not actually the case (and of course, it doesn't work on the date field I want to use it on). 

Does Adobe even do any development on Marketo anymore? It feels like it's stuck in 2018.
