Command Central Stacks multiple product installation on a single host

I need to install products to different installation directories on a single host. I understand that using Command Central this is possible. However, do stacks support this type of configuration? I am using Command Central verion 10.5.

Whenever I try to install a second SPM to the same host (different installation directory) I get the following error:

Hello,
Yes - this is possible either via stacks (as well as using the classic UI). It’s important to make sure that installations having different install dirs are not part of the same stack - this is even included as validation in the upcoming 10.7 release.
Back to the error, it seems that the template used for provisioning the second installation is most probably pointing to the first installation node alias. Please make sure that the second node being provisioned has different node alias and different SPM port.

Thanks,
Serafim
