Custom ADX?

I was curious if someone could customize the MT4 ADX to where I have the option of changing the +DI and -DI levels? For some reason when I change the ADX from 14 to 7 it doesn't affect the +DI or -DI levels.

This will be a big help to the system I am working on so any ideas, suggestions, or willing coders would be greatly appreciated.

Thanks!

I don't if this could've fit what you needed.
