Greetings to all,
I’m asking you about naming episodes "Off-Series" for a series.
To explain my case, in the series "Candice Renoir".

There are two "Hors-Serie" episodes of 1h30 each between season 10 and season 11.

And my question is: How numbered are the vehicles after season 10 and before season 11?
I tried "10.HS1" but they go before season 10.
Thanks for your help.
