Merge a Premiere-Elements project into another project I want to create reusable video projects and merge them with other projects. For example - create an ending with a copyright notice, a website url, and some more information, and then use that as the ending for multiple videos.

Of course this can be done by simply merging the video output (as I've seen suggested on several threads), but that would reduce the quality. Is there any way to merge a project into another project so as to preserve the quality?
I'm not sure if that can be done in Premiere Elements. In Premiere Pro, you can import sequences from other projects, which would accomplish what you're asking for, but as far as I know, you can't do that in Premiere Elements.
