Macro in template which defaults to {HOST.CONN}

[Gijs007]

I'm trying to monitor a service, which normally uses the same IP as the agent. However in a few cases the IP is different.
To make this easier to configure I want to use use templates with macro's. I'd like to create a macro inside this template called {$serviceIP} which has as default value the value of the {HOST.CONN} macro. (The reason for this is that if I'd use the {HOST.CONN} macro directly in the item key, I can no longer override it.)

However when I configure this for some reason the {$serviceIP} macro has no value. It simply contains the text {HOST.CONN}, instead of the IP...
How can I make this work as intended?

Exactly, so that I can use it in a template and when needed override it on the host level.
Apparently this is not supported. Is there another way to accomplish this?

So you want to use macro as a macro value? That's not going to work......

Basically. What I want is to take the connection details of the host and store them in a macro, so that I can override this macro when required.

I have the same problem (I use zabbix 6.0) and I wasn't able to find a workaround.
Have you find a solution, Gijs007 ?

I cannot believe that this is not supported, it would be such a neat feature...
