If by "fully customized" you mean defining species, rewards, etc. individually then you can't. This editor isn't able to do that because save edits cannot achieve that in general. Raids in SV are derived from a seed and a fixed set of tables present in game's files.

If you want to:

• create a ROM hack - you will have to modify those tables
• encounter a specific Pokémon available in base game - you will need to find a correct seed and inject it using PKHeX, you can use RaidCalc to search for seeds that give specific Pokémon/rewards

Thank you for your fast answer ! 

But I successfully created a 7* Charizard event using the files in thisBut I successfully created a 7* Charizard event using the files on this website, can't I just create a custom raid with only the choice of the pokemon ? Like if I want to create a Gholdengo raid 6 stars ?
And what does this thing exactly (screenshot above) ?

We don't have publicly accessible information relating to how to create your own custom raids.

If you have any background in hex editing, you probably can do that to the event raid files, but there is no tool nor guide relating to how to do it at this stage.
