Proxy Path question

I’d like to have the proxy path ‘/tools’ be set to goto Usermin on all new domains. I know how to do it manually, but when setting up a new domain, I don’t always remember to do it. I looked all over but couldn’t find where to set it to automatically do it. It seems like it should of been in the Server Templates.
If someone could point me the the right spot I’d appreciate it.
