Follow-up From Repeated Group Data

I am building a simple app that has a registration form and a follow-up form where:

  • Registration: We have a form which asks how many tasks one is supposed to complete, followed by a repeat-group question asking the name of each task
  • Follow-up: Is a Task reporting update form which is used by the teams to report on the status of each registered task by the end of the week.

What I have so far
I have managed to implement the repeated group very well and also managed to have the task names from the repeated group bunched up together in a comma-separated string using the join() function as mentioned in this post.

The Major Challenge
The challenge now is in the follow-up form I cannot seem to be able to retrieve each task in a repeated group again (or even list them all but separately) where, I need to mark the status (status can be completed, pending, or not-started)

Any information or guidance on how I can achieve this?
