Systems Classifications

[mshoai]

In Revit MEP, Storm & Sanitary piping have the same system classification, both are defined as sanitary.
Is there a chance  Autodesk, to come up with a separate system classification for Storm?
In real world application Storm is a separate , independent system from sanitary.
And in Revit, to separate these two (sanitary from storm) can turn into a time consuming process, by creating different filters to have them to show independently.

With limited system classifications, is there any intent to include additional system classifications? Additional systems should include: storm, process waste, fuel gas system (for natural has & propane), medical/lab gases, and there are others that would be desired.

This is just a bit of what is used in the water/waste water treatment engineering industry.  a clear way to know what system to use for any of these would be great.
