Hi Community,

I'm hoping for some advice from folks here.

I am an instructor and my students often come back and take different classes with me...so in my import file, I have course_type, course_date, and course_city, and the unique identifier is the email id. I am wanting to ensure that course_type is captured in each duplicate record because the duplicate record means the student took another class with me. I was initially thinking tags would be the way to go. But when I go to import these records, how do I ensure each instance/duplicate captures the unique course type and doesn't overwrite the previous course type? At first, I was thinking instead of making course_type a Custom Contact Field, I would remove course_type from the import as a custom field and assign the course_type as a tag instead. And each time a duplicate is uploaded/found, it would assign a new tag for the new course_type. I was thinking I'd need to do a separate import for the duplicate records for this initial import of 10K students. In that initial import, I have about a thousand duplicate records which are students who took multiple classes. 

Also, when I upload a duplicate, I'm ok if the course_date is simply updated/overwritten with the most recent course date. It's the course type that needs to be additive and preserved so I can design custom campaigns around those and for students that have taken multiple courses. 

Please let me know the best way to do this. I can see this also compounding when I start offering online classes through LearnDash. I will need FluentCRM to store that as a new course_type and not overwrite the previous courses/course types taken.
