DS2 introduces a lot of great things, but SM was not one of them. It unfortunately limits the amount of fun you can have on a single character. You can use that ring that takes all the souls, but that's probably the only workaround.
I was just playing a level in Death Stranding 2, clearing out some bandits stealthily, but then I saw they had a truck in their camp... I cleared the rest of the camp out by running the bandits over one by one.
