How would I overwrite player's saved data w/ data store 2

Hi, I have always wanted to know how I could add values into the player’s existing data like so:

_G.PlayerData[player.Name] = {
["Power"] = datastore2("power", player):Get(0);
["Gems"] = datastore2("gems", player):Get(0);
}

I want to know how to overwrite the player data which looks like above, into this:

_G.PlayerData[player.Name] = {
["Power"] = datastore2("power", player):Get(0);
["Gems"] = datastore2("gems", player):Get(0);
["Pets"] = datastore2("pets", player):Get({})
}

If anybody knows can you please help me, thanks :slight_smile:
