If I'm understanding what you're saying, I don't know an automatic way to do this in Premiere Elements, Phil. (I'm kind of confused by your wanting to change many photo duration to "the same new duration which will be different than many others on the timeline".)
If you're trying to create one slideshow where every photo is, say, 4 seconds long and another slideshow where every photo is, say, 5 seconds long. That's possible. You can do that by changing the Still Duration preferences before you import each set of slides.
But it sounds to me like you're trying to adjust the duration of a set of photos and yet still have the photos in this set be the same duration as each other.
If you can be more specific, I'm sure we can show you the simplest solution.
