Row Level Security Multidimentional Access

Hello Everybody,

I want to talk with you about the best way to built a security concept based on mutiple dimensions.
e. g. we have a list of users which should only see data based on their country/region, their product line and their vehicle line.
If we define a user to see for example only EU as a region and light vehicle as a vehicle line but a * in the product (Mean he can see all the product in EU only for Light Vehicles)
I used a code to do that but it looks too overwhelming and hard to update.
I believe there is a better and performanter way to handle my problem.
Thank you for your ideas!
