Ultimatum/Trials of sekhemas Upgrading

I probably speak for no one and probably should be put in jail for asking this but it would be nice if we had some way to upgrade our ultimatums and baryas to make them harder and more rewarding. Currently it feels almost tedious to grind them out without much challenge at the point of having a complete build. Adding more variety and freedom of challenge to players would be a good thing in regard to this.

I know you can get special ultimatums from Trial master but they still do not do much to the actual gameplay itself. If we could Vaal orb the keys to increase monster level or add modifiers to the barya/ultimatum it could add to some much more needed fun to these game modes.
