Clash Detection update rules?

Question: Can the rules in a clash job be updated without importing a rule set?

In Clash Detection, our rules are managed in a central location for all projects to access. When a new clash job is created, the rules are imported to that job based on the existing schema data from elements that are currently in the dgn file. Let say I have just steel in the model. Later in the life of a project, the content in the dgn file could/would be more populated with additional data, lets say pipe and cable tray, that would require more rules to be added to assist in the suppression of the results. Or if a new set of rules was added or existing rules were modified.

The issue I am seeing is that it is not possible to update the rules based on the current data in the dgn file, or is a keyin available that can do this. The only ways I know to get updated rules is to either build them manually, import a set of rules into the clash job, or make a new clash job. A mechanism to update the rules of an existing clash job just like the import of rules when a new clash job is made would be very beneficial.
