Highlight unmatched/forced geo levels to facilitate cleaning

[MathildeMousset]

Is your feature request related to a problem? Please describe.
Someone enters geo data. Sometimes the data matches the levels from the imported geobase, sometimes (often) they don't. Someone wants to clean it manually (i.e. it's not Patrick or me using hmatch to clean it, probably the epi that receive their data). They cannot see which data matches the geobase, and which needs to be corrected (if possible at all). It makes cleaning geo data very painfull.

Describe the solution you'd like
Would it be possible to have a different format for unmatched levels (in italics for exemple, or a different colour of text), like when they force a level (ignoring the warning). Ideally this would be done with data validation, and thus dynamic.

Describe alternatives you've considered
A button (perhaps within the geoapp, or near the geoapp button in the ribbon to click and apply this formating when clicking. This would apply a static formating, i.e. if they correct the levels, they need to click on the button to revert the formating to normal for cleaned data, or to see new data that was added.
