How to have mix "movies" + "shows" in one folder

[WestAus]

For example I'll pick Star Wars - there are lots of movies, TV series and a few specials.

Love this example. I was initially going to say Breaking Bad, Better Call Saul, El Camino.
There's also plenty of similar content in Au under the "Underbelly" umbrella. Seasons, 2 part mini/movie series, feature movies.
Even an actor folder, i.e. Paul Hogan. He initially had his own comedy TV series, + other movies before & after Crocodile Dundee. Why have it scattered.

My sons just turned 22, wasn't interested when this stuff was on (incl GOT). His about to motorhome around Australia, setting up a nas for him.
I could tell him before he leaves to make sure he watches the others, that their in the other section, but doubt he'll remember when the time comes.
But if there all in the same folder....

So how would I set this up? Movie & Shows library option, pointing towards;
>Breaking Bad Series
>>Breaking Bad
>>>S1
>>>S5
>>Better Call Saul
>>>S1
>>>S6
>>El Camino
