No.

Well thats what scope's are for. If you're using qmake from Qt4 it
solves all your problems. Add a scope for each machine you need to
change the variables. Set the variables in each scope apropriately. Now
all you need to do is change the lineedit with custom config values in
the subproject settings dialog. Or to use it globally stuff a line like

CONFIG += <scope>

into .qmake.cache and put the file into the top-level project.

And if you use a versioning system, make it ignore the .qmake.cache and
instead add a template to the version control system. Then on a new
machine checkout the project, rename the template change the scope and
be happy.
