D-H Groups for IKE of Azure Gateway

Hi,

Does anyone know if D-H groups for the IKE of the Azure Gateway higher than group 2 are possible yet? I've seen a few people asking this same question on other blogs, but no clear answer yet! http://azure.microsoft.com/blog/2014/12/02/azure-virtual-network-gateway-improvements/

D-H group 2 does have some vulnerabilities that can be avoided by choosing a higher D-H group.

Thanks
