Hi,
My company uses a matrix style hierarchy where we look at client and country on separate dimensions as per the below image.

I'd like to recreate this view in Anaplan (without the sparsity). Where client leads can see their client across all countries, and country leads can view their country across all clients. I'm thinking of using a numbered list and concatenating client and country, then mapping each list item to a country item and a client item. Is there another/better way that I haven't considered?
Any advice would be great!
Thanks,
Nic
