Change Track Length (Custom Radio)

[Spyder Arachnid]

So I've been using Old World Radio and then changing all the tracks to different music genres and such, to make my own custom radio stations. But I ran into a small problem.

 

Seems some of the tracks get cut off if they are too long. So I'm trying to figure out if there is way to extended a track to make it support longer songs. I was checking FO4Edit on it, and I don't see anywhere to change the track length to match my new tracks, then again, I'm a complete newb with this kind of stuff, so figured I would ask and see if anyone else knew how to do this.

 

I just want to change the allotted length to allow for longer tracks. I don't even know if this is possible or not, or if I just have to use shorter songs for it, but thought I would ask regardless. Thanks for any help you guys can provide.
