Add the ability to edit/remove webinars in the drop-down of webinars available when using the copy f

In the old platform I was able to edit the list of webinars in the drop-down of old webinars.  On the new platform, I have no way of editing the list of webinars in the drop-down of webinars to copy from.  I would like to remove some of the old webinars so they are NOT used again.  I am replacing some of my templates.
