Hi,
As c.pfaffenbichler said, there is no text option in PS for a vertical alignement in text blocs. There is a workaround that might help but it involves Illustrator:
- Create a text bloc in Illustrator and set it up to align text vertically (from the "Text "menu ), you can still use justified text and so on.


- Copy that text bloc with ctrl+c, and paste it in PS as a smart object. Then align that smart object in the center of your PSD.
You can probably optimise your workflow better if you create an illustrator file with many artboards (with a centered text bloc on each artboard) and then placing this .ai file in your psd.
Just select the right artboard every time you place your .ai file in the psd.
That way you could edit the ai file for all instances on your psd.
Hope that helps.
Regards,
