USGS Water Services Data Sources and multiple queries

I’m still learning Grafana, so maybe this is an obvious mistake on my part. I added the USGS Water Services data source and this works great if I have 1 query but I’m trying to add multiple rivers on the same chart. Maybe it is a limitation of the data source packs as they note only 1 target supported?

Were you able to resolve this issue? I’m running into a similar challenge. Thanks!
