Maximum on list of values of Business Classification

Summary: The Business Classification holds data fields on Category and within Category one can add Sub-categories. There is a maximum to how many Sub-categories can be added (250). For the country of France we almost hit that maximum. We needed to add this for reporting on TAX in France. However, other countries also have sub-categories and adding them becomes problematic because we would exceed the 250 maximum.
I added an EXCEL with the French sub-classifications in use. These are publicly available.

Q: would it be possible to increase the number of sub-classifications? Is this the route to ask this, or should an idea be logged?
