Can you save channels as favorites in Pluto TV on Flex?

I started using Xfinity Flex today, and so far Pluto TV is my favorite app, but scrolling through all those dozens of channels to get to the channel I want is such a chore (Buzzr is a channel I like a lot, for example). Is there a way to save a few channels to a "favorites" in Pluto TV? I don't see a way to do it, or a favorites section, but it's a feature with Pluto TV in Roku and on the Android phone app version of Pluto TV.
