Salesforce integration should not change vote count

Currently when you link a Salesforce case to an Aha! Idea, it increments the number of “votes” by 1. Why does it do that? Can we configure our instance so that it doesn’t affect the vote count? Since our Aha! Portal is internally-facing, we’re currently using the “votes” as a way to measure internal perception of value, and have a separate custom field to track # of customers requesting the idea. We don’t want to conflate the two metrics.
