Feature to add all episodes of a series to user list

It would be very helpful if we could add all episodes of a series to our user-lists in one click.

This can be designed in two ways; one or both can be implemented:

First. On the main pages of TV-Series, the existing button for creating lists

when dropped-down could show an option such as "Create new list including all episodes".

Second. There is a lot of free space on Episode Guide page, where the same button could be placed, but only with one option: Create new list of all episodes.
