Using Blueprints with vCloud Director endpoint

Hi,

I have created a blueprint which has a CentOS 7 client and a Windows 7 client which are cloned from vApp templates, this deploys new VMs but in new individual vApps. So if I stand up 5 CentOS VM's I end up with 5 new vApps with one VM in each. What I can't work out is how to create the 5 VMs in either a single new vApp or an existing vApp. Is there an easy way to configure this?

Regards

Rob
