Is there a way to set a setting in the option inspector to a path that is relative to some global Mathematica variable?
I'm trying to set up a default stylesheet by setting
DefaultStyleDefinitions to a style sheet located in
$UserBaseDirectory/SystemFiles/FrontEnd/StyleSheets. I need the setting to be independent of the path to
$UserBaseDirectory because I'm using the same settings on different machines where my user's directory has different names. But setting it to a value containing
$UserBaseDirectory didn't work.
