[Q] Editing ROM Files [PRO help]

[KeboPR]

For those Pro's out there.. Right now there are various roms that feature a mod for Call Recording in phone app menu for Sprint Galaxy Note 3 running 4.4.2

For example;
1. http://forum.xda-developers.com/showthread.php?t=2671779
2. http://forum.xda-developers.com/showthread.php?t=2669126


My question is;
Is there any POSSIBLE way of extracting that mod from the files from those ROMS and add it to every CyanogenMod Nightly Builds (Manually)

Thanks in advance!
