You have to load them incrementally to the KnowledgeBase one at a time.

You can have multiple RuleSets in one worksheet, please refer to
documentation.

The first time you load all speadsheets into a KnowledgeBase will take
sometime, there is no avoiding this. However once this has been completed
once you can serialise the KnowledgeBase and therefore load much quicker on
subsequent uses. I assume the rate of change of rules is much lower.
