AD Self Service Plus Certificate

AD Self Service Plus Certificate

Is there any way to create a certificate request that contains a certificate template or anything other than a .csr?

I want to sign the certificate from my own Certificate Authority but the web enrollment doesn't allow using Cryptography below windows Server 2008 and thus will not issue the more secure Certificate's from the web enrollment using the .csr as generated from the ADSS web page. 

Thoughts or work around?
