DAX measure to group weeks together

[jennif13]

I am working with data from a higher education data source and I am having trouble figuring out how to group items. For example, our modules last 4 weeks. I am trying to group Week 1 discussions, Week 1 assignments, and Week 1 assessments into a group so an average can be calculated. I am having trouble because I have old naming standards and items that are named something unique for that class. I am just not sure how I can standardize the names to make them filterable. I don't know if I should be using a hierarchy, a filtering DAX measure, or something altogether different. Any help would be appreciated.Sample table
