sln build runner: configurable vs version

Is Visual Studio version supposed to be possible to replace with a configuration parameter in a template?

I want to reuse the same template for two projects. The template does include a script runner (powershell) and the sln build runner. One project should compile using vs 2012 and the other project should compile using vs 2013. Is it possible to reuse a template which uses the sln build runner?

When I try, the gui doesn't allow me to replace the vsversion in textfield in the template with a %parameter%.

Using TC 8.1.4.

(btw, this is a question, sorry forgot to mark it as such)
