Importing Predefined Choices for Radio Buttons

Importing Predefined Choices for Radio Buttons

Hello

In the form builder for loading multiple Radio Buttons, you have provided - Import Predefined Choices as an option
But I am disappointed it is limited to inbuilt list within your software and does not appear to have the ability 
to import our own custom list say from a csv file that I was hoping for

Is there a possibility to extend this feature to my expectation or am I missing something here?

Thanks & Regards
