Lock certain group classifications to specific event types

Would like the option to lock group classifications to only be able to select specific event types when creating a request. A few examples:

1. Group Classification A can only select Event Types 1 or 2.

2. Group Classification B can select Event Types 1-5.

3. Only Group Classification C can select Event Type 6.

Despite outlining our event types to requesters, they regularly get it wrong. Would like to lock their classifications to only allow them to select specific event types in order to make our calendar easier to keep clean and maintain order.
