Persisting files in Team work spaces

Hello, I have a collection that has multiple requests which are submitting data files, images in particular.

Is there any way to store the images in team work spaces so they could be used after sharing?

If not, is there a way to fetch the image and attach it programatically? I could not find a way to put a reference instead of a file upload in the form-data/field value.

Any help would be appretiated
