Video Overview Instructions for Xseries or other Overview Pages

For this page:
http://edx.readthedocs.org/projects/edx-partner-course-staff/en/latest/set_up_course/setting_up_student_view.html#add-a-course-about-video-to-edx-org

Instructions do not clearly indicate how to upload an About Video for a series overview page, like Xseries. These overview pages do not have a "Studio URL" the way a course would. The field in which the Studio ID URL is required does seem to have some requirements about how the field should be filled in. In other words, I could not simply type "Marketing Analytics Xseries Overview" or I will get an error message. But if I type a "fake" URL like this one "https://studio.edx.org/course/MarketingAnalyticsXseriesOverview", the system will accept.

We should find a way to instructor course teams on how to fill in this field in Veda so they won't get errors and we'll be able to tell which video they are uploading.

Thanks!
