Default Physics Volume, Water Volume

Hey guys! I’m new here so I am sorry if I break some rules. I’m running out of places to ask so I am also sorry if it is a bit off topic for this chat. I’m trying to make my own swimming system, a little primitive that the Hyper has in his product but still.

I’m using Water Body River without transforming it into Blueprint Class and I noticed that my Water Body River is not a Physics Volume and therefore it is not changing the Movement Mode to a Swimming . I sought for solution and most of them require either placing Physics Volume that will be a Water Volume into the scene which seems a little robust or making the Water Body River into a Blueprint class do whatever in there. Is there a more elegant solution. Can I somehow set the Default Water Physics Volume in my level or project without making my Water Body River a blueprint class?? Thanks for reading the message

DId you ever find a solution to this?
