Feature request: Associate library media items to widget

I use Embedded and DatasetView widgets a lot to create more complex laytouts but currently I need to associate manually the files from library to the players, which is a very tedious and hard to handle task. Every time I schedule a layout of that kind to a new player, I have to check which files are used, go to players page and associate one by one.

If It were possible to associate files from library to those widgets or at least to the whole layout, even if I need to use the ID instead the name to point to this file, the player would download the files automatically, so any new player would be scheduled to the layout with ease.

Any chance to have this feature on future versions of the CMS?

Thank you!
