One feature I would LOVE to see in your games is a way to build your own Auto Level Up paths where you go through the whole leveling up process and save the template so you can leave it on auto while you are playing.
This would be especially nice in the Rogue-like modes because you are leveling up once every 15 minutes there and doing the level up process for 6 characters every time distracts from the game play experience
Assessing how levelling experience can be improved is one of the reasons for this poll. What you mention sadly won't happen in Kingmaker and WotR, but it's not out of the field of possibilities for Rogue Trader and future games. I'm not making any promises or giving any ETAs yet, but we're researching what can be done in this direction.
