Can a field name be updated based on another field value in dialog?
We have a problem from the stakeholders with a complex component, the component has a multifield with a number of product fields like sku, image path, description, etc. The authors wanted to make it collapsible but also wished if they could see the sku number in the Collapsible title 'Collapse' to expand/collapse and edit a particular sku. We are using AEM 5.6.1 version.

I made the fieldConfig 'collapsible' but I am trying to find a way to update the Collapse name appending sku number to it. Any suggestions for this problem would be helpful.
