Needing a save file

[nburton10]

I’m new to this, so I apologize if this is the wrong place. 
While I was gone for business my 1 year old got ahold of my switch and dumped it in the toilet, where it set for awhile. Got a new switch but Pokémon Sword does not back up to the cloud, so 200+ hours gone.  I’m wanting to play the new DLC but I do not want to start from scratch. Is this even possible?

Thanks for the help.

In my logic you cannot "overwrite" a savefile just like that. The storage data now seems to be account and not module bound.

My solution was therefore, Non Shiny Choise Band / Speccs Mon and rushed through the story. Haven't seen a Nintendo Account + Pokemon Savefile yet.
For the save files themselves (copy Pokemons or the complete boxes and paste them into your memory)

If there is a better way, or if I miss something, I would be interested in it as well. My English is unfortunately not good enough to be able to use Google correctly for this topic.
