I don't think there really is a solution for this. PS and ID are very different programs in the way they work. Also, a lot of the things you can create and do in Indesign, you can't (or won't work) in Photoshop - and vice versa.
I have created a few flyers as both Indesign and Photoshop versions - but it's really a lot of extra work. What I did, was create the flyer in Indesign, export it as a PDF, then open it in Photoshop, and use it as a faded out background to do the design once more on top of, in Photoshop.
So I created everything again in Photoshop, with the PDF as a help guide in the background. I really can't think of any easier way to do this... anyone?
