That's not that hard to do.
When you retrieve all the rules, the can call the first rule #1, the second rule #2, etc.
You can also use the rule description and add your own tag. For example, you could use a description "workstation", then to do a change, get the rules, update the one with "workstation" in the description, and then put it back.
There are no issues with scale. There might be an issue with how the rules are organised to make updating them easy ...
