can I change max level from mpq editor?

[afis]

I would like to know if it is possible to change the "Hero - Max level" stat through mpq editor. I figure the data must be saved somewhere in the map so it should be possible to change but have to idea where. or if you don't know where it is maybe someone knows of a trigger that can be imported to change this.
I am asking because I am playing an rpg in which the max level isn't high enough to beat the higher level areas and would like to be able to beat it without resorting to more serious cheats.

I'm just gonna pretend you know how to extract/insert files... If you don't, just say and I (or someone else) will help you out.

1) Extract the file called war3mapMisc.txt from your map.
2) Find the line "MaxHeroLevel="
3) Change the value to whatever.
4) Reinsert the file.
5) ???
6) Profit!

Thank you for the help, now I can continue playing.
