Describe a description of the new feature

Hey,

I looked around a while for the optimal solution to install apps on my Huawei device, that couldn't be installed from neither Aurora nor F-Droid. I then decided to go for AppManager because it can open app bundles from APK Mirror and is more useful than any other app.

However, sometimes I have the need to unbundle some apps that comes as bundle only – which seems to be the case for a good bunch of apps released in the past couple of months. So instead of.apk, APK Mirror lists more and more bundled apps.

What I'd like to do is to share that app bundle to the AppManager installer and have the option to "unbundle and save" the .apk file instead of installing it; but have the usual functionality of AppManager installer to select the right splits and so on

Describe the solution you'd like

Describe alternatives you've considered

As a workaround I for sure can install another app to solve this task but having everything in a single app would be the easiest way to go. So please add the feature to save the APK to a certain location instead of "just installing" it.
