Allow the use of relative dates in workflow/smart list criteria
HubSpot Marketing currently only allows smart lists and workflows to use Deal date fields as absolute values (eg. August 17, 2017). This makes it very difficult to create smart lists and workflows based on aging deals or moving time ranges.
The ability to use relative date fields (eg. today, older than 2 weeks, less than 2 months ago) would open up so many possibilities in dynamic workflow enrollment.
