RAR - Attached file to the role definition

Hi,

In the "Configuration" tab -> Miscellaneous.

I don´t understand what´s the function of the option "Allows you to attach files to the role definition".

You can attach files only in the Testing stage, but if chose "Yes" or "No" in this option, the system allows you to attach files in this stage.

Please, someone knows the real function of this option?

Thanks!

Kind regards,

Sergio
