Change Account icons in v1.8.1

Account icons

With each new update I lose all changes made regarding Accounts icons.
Would it be possible to create something custom that makes all the changed icons “LOCKED”?
Every time I have to go search for the procedure to see where the theme folder is (I can't find it this month), take the icons from my theme, override them with the new one!
It is really frustrating!
