Tagging customers in JPD

[Dakota Beres]

I am searching for the best way to track customers related to ideas in JPD. We started with a global field (our customers often span multiple products) but I am not convinced this is scalable. The limit on multi-select fields is 1,000 options and while we could keep it within that range if we had to I am not sure it is the best way.

How are other teams tracking many customers that span multiple products?
