Since directly filtering by send_time is not supported in the new /campaigns endpoint, is there another way to filter based on send_time? Seems a bit odd to be able to filter by the other date fields like created_at and updated_at etc., but not send_time.

The usecase is getting all the campaigns sent within a date range for example. Getting all the campaigns and then filtering manually is an option of course, but that’s multiple HTTP requests (pagination etc) and a lot of data that’s going to waste
