Rooted Galaxy S4 with GPE ROM - OTA Updates ?

I had to send my GS4 away for repair recently but before I sent it, I was rooted and running the GPE ROM. While I ran the 4.3 version, it automatically downloaded the OTA Kit Kat update file. However, when I told it to install, my phone just restarted and booted into the custom recovery and didn't do anything.

So I've since had my GS4 back from Samsung and I'm looking to run the GPE ROM again, but is there any hack or tweak to allow it to install OTA updates like the real GPE devices do ?

Any help would be greatly appreciated !
