Install SQL 2014 Server (+cal) version

I have SQL Server Server licenses (not the core version) available from way back and software assurance.  I need to do an install of SQL 2014 using one of those licenses.  The only way I see to run with that license (which has CPU limitations) is this:

1. install SQL 2008r2 Enterprise
2. Upgrade to SQL2012, specifying the server license during setup
3. Upgrade to 2014.

Is there a way to do this directly without all the steps?

Thanks
