Configurable custom links on the host detail page

A very "welcomed" feature would be a simple customizable button in the agent's detail page: a button like the one "update now" for the agent BUT that I could modify, where I can for example point to an external page e.g. "Go to inventory" or "Go to NMS", and where I can create a link something like:

https://foo.bar/$agent_name

In this way I could simply forward the user to another tool that for example could manage the update, or just another tool whatever it would be.
