Generate screenshots of multiple screen sizes for store landing pages

Description of the feature request

Before publishing the app the workflow step would create screenshots of the app in multiple size (by user’s preference), then generate all the marketing materials that appear on the landing page of the app in Play and/or App store.


Creating media/marketing materials for each device and store can take more rounds with deigner(s), especially in case of last minute of bug fixes or when you publish on a regular basis.

Thanks for the #feature-request @aeneis! :slight_smile:
