Cooking Like An Htc

[Fa310tx]

Hello...
From any threads that I've read about cooking your own omnia rom, it seems like you need to extract and rebuild files, manually, dragging into other programs. Plus, I've read about having to remove stuff from multiple text files. That seems like quite an undertaking when it's just click-click-click for htc.
Is there not a graphical program, like ppckitchen's buildos for omnia cooking? I've made multiple custom roms for htc phones, but manual is a new world for me.
Also, I'm guessing we don't have the ability to update files, like with ppckitchen's buildos.
