Shared Metatrader folders

[Forex Trader]

I have three different installations of MetaTrader in three different computers. Whenever I make a change to a template, expert advisor, indicator, sounds, etc, I have to do update the files in each station. I want to to be able to make a change only once, in one station. Can MetaTrader be set up so that the "expert" folder (and other folders) are queried from a shared network drive? Thank you, Juan
