Hi Rocky,
Not sure if someone is just going to give you code however i have done something like this years ago in which would upload a csv file to a record and then it would go and create related records to that record and associate them
Having basic experience with plugin development and c# should help you solve it.
you are effectively retrieving the annotation record, deserialising the CSV file and iterating through each line doint what you need to do.
If the Plugin route is not ideal, this COULD be a candidate for a MS Logic app that would file on the creation of a record (note) in dynamics!
Thanks
Good Luck
Jonathan
