Add Filter Option Under "Other Contact Dates" to Included "Last 2,7,14, Etc. Days"

Presently under the filter option "Other Contact Dates", there is just an option for a date range. It would be great to have a couple of options like "Last 2 Days", "Last 5 Days", etc. This would be a filter you could then set up that would be dynamic, so I could save that filter and have easy access when I just want to see who I've contacted in a specified period of time, and that time would dynamically change. Hope that makes sense.
