Comm Manager CDMA to GSM switch

[notanerd1411]

I thought I had seen that in a few Custom ROMs the cooks have added a switch into the Comm manager to switch back and forth between CDMA and GSM.. I was wondering if there would be a way to add that to a custom rom that didnt have that option.

Currently I am on MM newest build and although i dont use GSM all that much it would still be nice to have...

Thank you in advance..
