How do you put two mods together?

I have an admin menu with the file name _missions.gsc but then i also have a roll the dice mod which also has the same name. and if i put in the same folder it would overwrite, so how do i add the admin menu to the roll the dice _missions.gsc?
thanks.

(im not sure if this was the right place to ask)

It's the right place to ask =3
Just put the codes from the admin menu into the _missions.gsc of roll the dice mod =p

so do i put the whole code of the admin menu after the roll the dice, without spaces, enters or other characters?
