Is there a way to edit the wave source in a "Water Body River"?

Hi!

In a “water body river” details I can’t find the “water waves asset” that is present in both lake and ocean. It seems like in a river I’m stuck with the waves source that are preconfigured but I’m probably overlooking something.

Is there a way to configure the waves in a river, like I do in a lake or ocean? For example the number of waves, min/max wavelength, min/max amplitude, etc.

Thanks!
