If a key is matched to multiple rules and it sets the same classification column, the user can control the order by ranking the most important rule last in the rule set. This is because classification rules are applied from bottom to top, so the last rule that matches a key will overwrite any previous rules that also matched the same key. Ranking the most important rule first or using linear ranking will not work, as they will not ensure that the most important rule takes precedence over the others.
