Multiple $INSTDIRs

Hi -

Is it possible to have more than one default Install Directory. I am trying to install files to both \programfiles\foo and also \inetpub\wwwroot\foo but don't want to have to manually insert the \inetpub... path in the SetPath statements.

Is there a way to create something like a variable $INSTDIR2 and assign it the \inetpub path?

thanks -
David

Var INSTDIR2
...
StrCpy $INSTDIR2 "mypath"
