Ability to instantly toggle shares SECURE <-> PUBLIC for impromptu file editing

I'd like to leave my shares set to SECURE 99% of the time, with an easy way to allow myself access on-the-fly to edit filenames, move files, replace files, etc..... but return the system back to a secure state with a click.  Ideally, I'd like something as simple as a button I could click, that would open-up write-access on my /movie & /TV shares so I can do what I need to do, then just as easily....click a button and return things to SECURE.  -I- am the biggest security risk on my network, but -I- also need to frequently fix filenames and replace files with better copies. 

A click-ON click-OFF  or toggle arrangement, preferably with a timeout feature, that returns to SECURE either after X-minutes or whenever it detects no activity...
