Dynamic Content Criteria Challenge - Case-insensitive

We have a unique process that loads in comma separated lists of event types into a custom contact field to appropriately flag specific connects for targeting/personalization. For example, we load "Men's Basketball" into a contact field for someone who has a "Men's Basketball" event in the next 7 days. However, we would also load something like "Men's Basketball, Women's Basketball and Baseball" for a contact who has all three events in the next 7 days, etc.

The contact field is being used as part of a weekly email that using dynamic content to identify those who have specific events listed in a contact field.
