Is it possible to call $VH_NAME in host templates for rewrite rules?

Hey guys is it possible to call variables in rewrite rules?

I wanna make a global rewrite rule for all my wordpress sites. I just switched over my webserver OLS.

So far iam happy with the results. But in order to finish my deployment i need to apply some global rewrite rules otherwise its going to take me to my next birthday to finish this process.
