Sprite Animation

How do you drag and drop sprites into the timeline to create and edit sprite sequences with a sprite renderer as the binding?

I've tried creating an legacy animation clip seperately, dropping sprites onto it, and then bring that into timeline, and that works, but the process is way too many steps, I keep forgetting how to do it. Also, you end up with an extra animation clip in your project (whereas other types of animation are just built into the timeline asset, which I like much better)

 

I'm talking about the way you can drop sprites directly onto legacy animations (for a sprite renderer with an animation component attached)

I was able to (sort of) get these types of clips feeding into timeline, but the setup is a ton of steps. What I want is to have a sprite renderer binding directly on the timeline, and then have the ability to drop sprites onto the timeline in the same way as I'm doing below.

 

hmm, if you could work on that it would be a massive optimization for those who work with sprite animations

as of now, you really have to rely on something like this (which is really good, but only works with animation clips) https://assetstore.unity.com/packages/tools/sprite-management/powersprite-animator-71177

what would be great is something similar for timeline sprite animations
