Add Collection Project requirement that allows one to include observations based on added-on date

Platform(s), such as mobile, website, API, other: website

URLs (aka web addresses) of any pages, if relevant: https://www.inaturalist.org/projects/new

Description of need:
I need to filter observations based on the upload date for a project.

Describe the iNaturalist community need that your requested feature addresses. Include screenshots, URLs, and other details to help us all understand the issue.
The Date Observed is available but “Date Created” is not

Feature request details:
In detail, describe the feature you are requesting. This includes its functionality, where the feature is implemented, and what it might look like. Screenshots or mock-ups are helpful. The idea is to have a concrete and actionable request which the community can discuss and vote on. It might change through discussion, but it’s much easier to iterate and talk about something specific.
It should work analogously with how it does in Explore or as “Date Observed” does on New Project.

Actually, it would be awesome to have as many as possible filtering options of Explore or even Export available on New Project.
