Allow to select a folder with images to be selected for import

In C1 mobile, when selecting an external storage for import it is only possible to select files, but not a folder that contains photos.

Would it be possible to be able to select a folder and then display the import selector similarly to SD cards (where I then can select or deselect the photos I want to import)?

Rationale: In the current file selector, the previews for the photos may not be available if the type of RAW file is not supported by iOS (or iPadOS), but is supported by C1. E.g., lossless compressed Fujifilm RAWs (for example from the XT-5)

Hence the only way to see what I am importing is to import all (or perhaps based on the date) and then once imported delete all those I do not want. The size of the iPad is limited, and deselecting at import is a lot more efficient.

Alternatively, would it be possible to enhance the file imported to show thumbnails for all RAW files supported by C1? (Although I think this is the worst solution, as you only see thumbnails, not previews which can be resized in the viewer)
