Can I return a list made from a release_date range?

So I am essentially trying to make a list of games that came out within say the last month, so far with the releases segment of the API I can return all of the releases on a single day.

Is my only option to have multiple functions, each with a different release_date, one for each day or is there a simpler way to do this?

[4.2.13] The date fields can now be filtered by a range of dates. The start and end date is separated by a pipe. Using one date will be considered as filtering for the exact date.
