Directly apply chosen document type, correspondent, storage path when editing / creating

[Biepa]

Hey, thank you a lot for creating the app. Works very well for me. :heart: I have sorted a few documents in the last days and wanted to propose a little change.

When editing a document and changing something like the document type where only one option can be selected I would like the UI automatically use my selection (as it already does) and then also do the "back" step for me, where I have to tap once to get back to the edit view. This also applies to the correspondant but of course not for something like tags.

Sounds like a good idea, I'll look into this!

It would also be great in the share dialog, when inputing data.
