We have a need to track one or more customers to an Idea so we can generate reports that show "We completed x items for Customer A" or "We have x items on the roadmap for Customer A".
Using a multi-select dropdown is an option but we have over 20k customers so this doesn't scale well and I am not aware of an easy way to import a list that large into a dropdown. (or keep it updated).
Insights seems to be another option but requires the user to copy in the Account from Salesforce. We are also not sure if we can accurately report on this data in comparison to a normal JPD field.
How are others solving this need?
