Other systems I have used that start with S , have at the top of the Summary Report as well as the Main Report a Total of each Category by the colour codes.
I would like to see it go one step further having a grid styled with Colour across the top then Systems Down the side. Plumbing, Electrical etc. So you can quickly see ie, Plumbing 2 Monitor 4 Repair/ Replace 1 Safety Issue
Electrical 5 Repair /Replace
