beginner's question: variable definition in apache config files?

is it possible to define a variable in an apache config file? that
is, I would like to write

myapp = /home/httpd/server/html/applicationrootdir

and then say

<Directory ${myapp}/subdir>
various
</Directory>
....and many other ones like it.

I have searched for a while, but not stumbled upon this functionality.
This would make it a lot easier for me to move trees to different
servers and/or locations. Even finding out that this is not possible
would be useful. help appreciated.

AFAIK No. Unless you hack the code of Apache that read the file.
But what's the advantage in doing so?

Then use a pre-processor to parse *your* 'config' file and produce
an ad-hoc configuration file. Sed is the first thing that pop in
my mind that could do it.
