Feature request: Share file to Waterfly application and select existing transaction

[dreitakter]

This is a follow-up to #207

I Like this new feature to share files directly to waterfly. Thanks for implementing this :)

Is it also possible to display a transaction selection View after choosing waterfly as a sharing target?
On top of the selection just something like "new Transaction" (current behavior) followed by the Last 50 transactions as list.

In my daily usage the Data Importer Imports all my transactions and I Upload the files Afterwards.

Keep going the good work 👍
