Favored Map Slots and Maven

I Love the atlas rework so far, not having to hope the "right" maps drop is so much better than what we had before.
Just one gripe or suggestion i have is that maybe you could reintroduce favored map slots so one can save their prefered maps and quickly access them from the side instead of having to look for them in the atlas.
And another suggestion i have is that maybe you could add a Maven passive similar to "Synthesised Stability" so that when you kill a map boss maven "witnesses" another one from among the favored map slots or, if that's too op, witnesses a random one
