[Automated Testing][Cucumber] Selecting a radio button with duplicate label

I am using Cucumber for Appian and I have a form with multiple radio buttons with the same label.

Example: A radio button with "Choose option" as a label

Documentation suggests I use: Given I populate field "FIELD_LABEL or [INDEX] or FIELD_LABEL[INDEX]" with "VALUE"

So I tried pretty much all the combinations with no success.

• Given I populate field "Choose option" with "VALUE" - This selects the 1st occurence of the label
• Given I populate field "Choose option[2]" with "VALUE" - Where I attempt to populate the 2nd "Choose option" in the form
• Given I populate field "[22]" with "VALUE" - Where I tried a couple of values for the index which were after the last known field over it in the form

Anyone know how to make this work?

Thanks,

Mat
