Filter instanceIDs based on submission date

I am transferring data from ODK to another application through API.

For this I am fetching the instances of an ODK form and then fetching each instance's details.

What I want is to filter the form Instances(InstanceID) based on submission date so that I don't have to loop through all of them.

It currently isn't possible to filter by submissionDate without iterating through all the messages. The way I'd workaround this issue is by using the Briefcase API to download and cache the submissions as they come in, and then process those cached submissions.

I'm going to move this thread to Features because this is a feature that we should add to ODK's API.
