Workflow and storage

Hello,

I have been using Lightroom CC and really enjoying the way it saved all my images to the cloud and my external hard drive. I was hoping to be able to use my videos stored in Lightroom CC to make videos in Rush, but I see now, that's not how this app works at this point.

Here's my confusion. I want to be able to upload my videos to rush and they will be stored (just like LR) in my cloud and in my hard drive, along with the videos I make in Rush. I don't want to lose these original videos.

So how to I use Rush as a way to store my videos in an organized way (hard drive and backed up to the cloud)? 
When I use my videos to make a Rush video, does it permanently chop and alter my original video files?

Thanks,

Katherine
