Hacking Adrenaline - Saving global settings, and importing Dexdrive saves?

[XC-3730C]

I just got Adrenaline set up on my PSTV and really like it. I am wondering how I could save settings globally for all PSX games such as controller settings (left analog as a d-pad) and screen size/filter, so I don't have to keep setting it up for every game, or the same game over and over.

Also, is it possible to somehow convert or import Dexdrive saves?

Thank you!
