Access named controls and variables from insert reference
If you are trying to customize the text for add row icon in a repeating section for example you cannot use named control values or form variables. Only Item properties are available. Same holds true for the insert reference function for other controls. The problem is that the value of the item property is not updated in a form until the form is submitted. You have to get the value from the named control connected with the item property or use a form variable to fetch value changes in the form while it is filled out. So if you want to change the text for add row icon depending on a language selection it doesn't work. To achieve this you need to have access to named controls or variables used in the form.

Thanks for your suggestion.
I will update this idea if there are any updates to share.
