Rename output of BI Aggregation check

I have created a BI Aggregation and a service rule to create a check showing the state of the aggregation.

However, the status detail only shows “Aggregation state is OK” and not what is checked.
I also tested the option “Display additional messages”, but the output is shown in the BI monitoring section only.

Is it possible to rename this output, for example to “Host State: OK” ?

As a business aggregation typically consists of several states, I cannot see, how this output would help. Maybe you can elaborate on your use-case?
