Given a list of Enrollment.MyOrgUnitAccessInfo objects, what is the recommended way to fetch each course's description?
 

I have a list of Enrollment.MyOrgUnitAccessInfo objects, obtained from the LP enrollments/myenrollments endpoint. I would like to fetch each course's description. I see an endpoint to fetch this information for a single course, given its orgUnitId; is there any better way (i.e. less likely to hit rate limits) to do this than calling this endpoint repeatedly? Thank you.
