I cannot use the data pre-loading feature to pull multiple instances with the same key value

One of the services we offer is case management. We usually keep a record
of every contact we make with a certain case (whether phone call, home
visit, referral, etc...). This recording is performed on ODK Collect, one
form per contact. Suppose On June 3rd, I called this case, and on June 4th
I paid them a visit, and today I'll be making another call to this case.
With data pre-loading, I was able to show a note on the form at the
beginning to see how we have contacted this case in the previous days.
Unfortunately, this feature only returned the first instance in the
attached CSV file, where the key value matched my case number. Although I
have two instances in the CSV file where key value matches the case number,
I was only able to display the first instance.

Is this a limitation of the new feature or is there a workaround to fix it?

Thank you.
