Hello Jessada,
Thank you for your message.
Unfortunately, the "Ask user permission" feature doesn't allow to identify the remote user yet. However, I'll forward this feature suggestion to our development department for a review to see if we can add it in our future updates.
Meanwhile, please note that you can set up some additional security features, such as Remote Utilities security authentication method that allows to enable the "Ask user permission" feature only for some of the users. For more information on how to set it up, please see
this page.
Hope that helps.
