Running multiple instances of ASP.NET Core Web API in Rider

Pretty self explanatory title. I've got an ASP.NET Core Web API project which uses Consul and I need to start a few instances of that project. Issue #1 it didn't let me run two instances in parallel, so I had to enable the "Allow parallel run" option in Run/Debug Configuration. Issue #2 Both instances are using same port configuration. So the question is about issue #2. How do I make the different instances use different ports in Rider?
