Systems to Avoid Differences

In SE4, you could set systems to avoid pretty easily from the map screen. I am ok with going into each individual system to adjust this. I am, however, missing the toggle that you could set in the planets screen, so that you could filter out planets in systems you don't want to go to.

Let me elaborate. I use the planets screen to send out colonizers. As I explore into enemy territory, I don't want those planets to appear in the list...a list I usually set to show empty planets, or empty breathable planets. It makes things very difficult now that I can't sort out systems I want to avoid.

I have tried to find a different way to do this, but have been unable to. Anyone have a workaround, or are we stuck waiting on MM to implement this in a patch hopefully?
