I can't find a solution for the following.
When you add a field e.g. 'Textarea' in Custom Field Group and expand it it will have a Label 'Textarea' (by default) and a ID field with 'textarea_039x04dhqzp5' (by default).
If I select content of the Label field 'Textarea' and start typing new Label name the text will change, but the ID field remains unchanged.
What needs to be done so the ID label changes automatically as I type the new Label name for the field?
I've tried to research that, but could not find a solution.
