Add arbitrary label to host discovery name prototype

[troffasky]

I am using a template which discovers Unifi devices from Unifi server with Unifi API. Unifi devices in Unifi are organised by site, of which we have 30 [on this first instance I am testing with].

This is the template I am working with:

https://github.com/artistassembly/zbx_unifi_network/blob/main/7.0/zbx_template_unifi_network.yaml

The issue I have is that Unifi devices do not necessarily have a globally unique name; they only have to be unique per site, so lots of "AP1", "AP2", "Switch 1", etc. The template is applied to Unifi per-site [this is fine, I don't want everything discovered], so there should be an opportunity here to insert a label in to the host names.

What I have tried so far:
- Set a macro on the parent host {$UNIFI.SITENAME}, and include this in the host visible name prototype. The macro is inherited by the created hosts [great!] but not resolved [boo] .
- Edit the hostname prototype on the parent host. Not possible, it's greyed out.

How can I achieve this?

It seems like anything potentially usable for this [user macros, tags] is not accessible in a way that it can be used in the hostname, even with Javascript preprocessing. Annoying.

I have been reduced to cloning the hosts created by LLD so I can give them sensible names, then disabling the LLD rule.

I'm pretty sure you should be able to take that user macro and push it into that json (returned from unifi) as new key-value pair... so you can later point a LLD macro to it...

If I have to edit the item to add this usermacro, that means it can't be templated :-/
