Missing Serial Number for some TV Series

[Emm88]

Bonjour

Feature request please to better name mp4 files

On top of the option of adding date could we please add the serial number of a TV program ?
(by serial I mean the address part after videos in the URL)

So we could save with the TV program name
Xenius
OR with existing ''add date'' function
Xenius-2018-09-28 15:10:00Z
OR
XENIUS-063945-041-A
OR
XENIUS-063945-041-A-2018-09-28

Thanks
This would be most useful for all recurring series

PS: Note I find the add date a bit buggy
Why does it had a Z at the end ?
Regards

Otherwise saved named are just incremented
