Grouping SSRS results by cell background color

Question

I have created a report in SSRS which shows Disk information on multiple servers, and it is set so that background cells turn orange if free space is under 20% and red if under 10%. I would like to have the RED cells (critical disks needing cleaning) at the top of the report.

Is there a group expression I can make to achieve this (grouping by back ground color or % < 10)? I couldn't figure it out. No questions on this online either from what I have seen

Thanks!

Answer 1

You can simply order by the percentage of free disk space ascending.

Putting this as an answer as I genuinely think this is it!
