Changing ROMpaths, a PITA or am I doing it wrong?

[DaveC1964]

So I wanted to change the path for ROMs.  I go to tools, but there is only an option to change ROM path for selected game.  I want to do it for the whole PLATFORM.   I can't find the menu item to "change ROM folder path for selected platform".  Does this mean I need to do it one by one for a few hundred games?  Please just tell me that I am just a noob and the easy way is to do...  Otherwise LB is really isn't very easy to work with and I thought that was supposed to be a big advantage of it, ease of use.

Select all the games in a platform with Control + A on the keyboard.
