How to Change Home Path in the Browser Perspective

Hi. I need to change the home folder in file browser for every user, from it´s default "/home/(username)" to another forder like "/public/(companyName)".

I found this can be accomplished by hardcoding the string window.parent.HOME_PATH" in js files, but the proper way seem to be modifying and recompiling the PentahoWebContextFilter.class file.

I'm right?

I was looking in https://github.com/pentaho/pentaho-platform but no sure which branch to choose and how to recompile it.

Thanks a lot.
