Select multiple / all Resources and drag to timeline / stage

I need create a few projects where using a slider a user can drag through a sequence of slides, similar to scrolling through a movie.

It would be great if I could select all/multiple Resource files (the numbered slides) and drag them into the timeline.

Bonus 1: Have the ability to set the duration and opacity of each Resources in the timeline, using something similar to the ‘Format Painter’ tool I suggested earlier.

e.g. Assign each resources the settings:
opacity 0-100 (0.5 second), duration (2 seconds), opacity 100-0 (0.5)

Bonus 2: Specify the duration of the sequence and have the Resources automatically space themselves accordingly on the timeline.
