Is it Possible to Shorten My DataStore Code?

Okay, so I have a DataStore that is currently 188 lines long. And while it works, I don't believe it's efficient, so I'm wondering if there's a way to shorten it.

Right now, the reason it's so long is because I'm saving every individual value into a table and then saving that table. I was thinking, maybe I could put all the values into a folder outside the DataStore and then save the folder. If this was possible I would be able to significantly cut down on code in my DataStore. It would also allow me to add new values easier and faster than before. Even if this isn't possible, if anyone knows an alternative, I would greatly appreciate it.

This might be a pointless question though, seeing as I have no idea how other people save data and they may have over 1k lines.

This is currently my code, you can see why I have so many lines now:

local DataStoreService = game:GetService("DataStoreService")
local Data = DataStoreService:GetDataStore("DataStore11")

game.Players.PlayerAdded:Connect(function(player)
    game.Players:WaitForChild(player.Name)
    player:WaitForChild("leaderstats")
    player:WaitForChild("SpeedMulti")
    game.Workspace:WaitForChild(player.Name)

    wait(1)

    local Key = player.UserId

    local Leaderstats = player.leaderstats
    local Speed = player.Speed
    local Rebirths = Leaderstats.Rebirths
