Hi,
this is in my opinion not really true. You can build your BI’s fully dynamic with regex and co. You just have to implement enough standards. With these standards you can do whatever you want and build your monitoring dynamically.
To do something like that please take a look at the BI guide → Business Intelligence (BI) - Reduce complexity with BI
and
Business Intelligence (BI) - Reduce complexity with BI
I understand that this is a lot of intial work and it can be frustrating to implement but you only have to do this once and then you profit from it and everything new automatically fits into place.
