Populate Parent List Field Values into Nested Form's Child List Field

Trying to populate the User-entered values in a List Field on the Parent Form to an identical List Field on the Nested Child Form. I cannot use Autolist Field Perks on the Child field from Gravity Wiz because I need the “-” button to enable the User to be able to eliminate the values not relevant to their application. Here’s images of a process developed for a similar purpose but it uses a Checkbox instead of a List Field. I’m trying to adapt this solution to the list field. Possible?

Did a bunch of exploring with this one on the ticket you have open with us but I wasn’t able to find a solution in a reasonable amount of time.

If other folks need this, let us know and we can prioritize this for an even deeper dive in the future.
