iOS save images/files to files (and other system hooks; Apollo parity)

[sixsixseven]

Is your feature request related to a problem? Please describe.
In Apollo for iOS, we could save images and other files directly (via context menu) into other apps (specifically Files for iOS) without first having to save into Photos.

Describe the solution you'd like
After long pressing on a photo or file, I would like to be able to save images/files into other system supported apps, namely Files for iOS, without first having to save it to Photos, and then moving it to Files.

Describe alternatives you've considered
Only current option is to save to Photos, then go into Photos and save where I really want the images/files. Very circuitous.
