Sub Sections In Power Apps

It would be great if you could create sub sections in Power BI Apps. 

Currently our sections in the power BI App are split out by each business area. It would be great then if you could create sub sections in within the existing section so we could group reports together.

For example we currently have a Finance section. It would be great if we could create another sub section in the finance section to group all our ECL reports into a sub section and then all our EIR reports into another section to make the App more uniform and clean. Currently you can only have a main section and no sub sections
