[Modding Question] Skill cost in Skill Trees screen

[Tsubir]

Hey there,

I have been planning on modding the Skill Screen elements and was wondering if anyone has any idea as to where the green skill cost number (that appears next to skill icons) is located?

I looked through skills.mnu but could not see the position of the cost number referenced, as I was looking to change it.
Perhaps it isn't possible to move it around? I have also checked skills.gdb to no avail, I may have missed something.

Any help is appreciated!
