Option to use template group in hosts settings

We are using the combination of hosts and templates to great effect, to have a set of sessions available on similar hosts.
However, if we need to add or change which templates the hosts should use, we must edit them one by one.
This is a huge task, as some of our vaults contain more than 10,000 hosts.

Being able to have the hosts reference a "Template group" will allow us to change the sessions for all similar hosts.
Please feel free to contact me if there are any questions regarding this request.
