[digiKam-users] How to make a one-click workflow: Resize selected photos and export them to remote storage?

[NeiNei]

Hi there,

I am looking for a one-click workflow with which I could
1. Select all pics with a 5 star rating in an album
2. Resize all pics of the selection to a given size
3. Export the resized pics to a remote storage  (SMB share of a NAS)

How could I achieve this with DigiKam?

Manually I could 1, 2 and 3. With BQM I could do 2. But how to glue all 
together to an one-click workflow?

Thanks for some hints in advance,
