Insert text slides into a project

Hi

I have hundreds of short video clips in a project.

I want to add a black slide and put some white text on it (rather than adding text to the actual video, which i see can be done).

Does PE have a function to do this?

And, if so, can I add it mid-point in my project? 

Slightly aside, I am finding when i copy and paste a video, mid-point, it pastes over another video.... so the only way i've found to get round this is to go all the way to the end, and paste it there and drag it all the way back again..... Is there something i'm missing here?

Thanks!
