First, if I may, I would suggest you narrow things down. Specifically, what does Lightroom not do that you would like Photoshop to do? Start there.
As to your specific question, if I'm understanding you correctly, you're having trouble because, as I've said before, Photoshop isn't meant as a bulk processing app
. So if your goal is to process "a catalogue of images in a timeline", you should continue to use Lightroom for that.
