Bomber escort in QC

Can anyone point me in the direction of the file I need to modify in order for a third party A/C to show up in the bomber escort option in QC?
I have JS QCed,and have added the plane(B-29) to the QC list,but despite being identified as a bomber,the darn thing dosnt appear for escort
Any help is appreciated
