Geocache log picture options

Hello,
please add third option for adding picture in geocache log.
Right now there are two options: "Take picture" and "Select picture". Second option allow select photos from gallery only. I would like to add pictures which are saved as attachment in cache which are saved in app hidden folder by default. I don´t want to change my folder for these attachments because i don´t want to see them in phone gallery.

Use case: There are caches with many stages and it takes many days even months to finish them. Save picture as attachment is save place to store these pictures and there is no risk to delete them from phone gallery point of view.
