Hi again!

So, I have a scene I want to begin at the end of another scene, but I need the rest of the previous scene to be gone. Is there any way to crop a scene so that the end of it is at the beginning of the timeline? I have tried, but everyone goes back to t-pose. And yeah, I understand why, but it's still frustrating. LOL Is there a way to "bake" the characters' stances and locations so that they stay put to crop back?

Thank you all!
