I am afraid that a custom pop-up could not be configured to be used for the nvalidFileType alert of the Editor. If you think that such option would add value to the widget, I would suggest you to log your idea on our Feedback portal. Based on the support it receives, we will decide on whether to proceed with its implementation or not.
