How to enable port fowarding in ports diff than 80?

Hello,

We have some apps that do not run in port 80 or 8080, and those ports do not show in the UI to do a port forwarding as it happens in port 8/80800. Is it possible?

In the service pages, I am able to click on apps on port 80 or 8080 and open it in the browser but the apps on other ports not, see the image below:

How can I enable/configure rancher to say the other ports is also http port?
