U4919DW, requesting firmware for PBP mode

I recently purchased and received my U4919DW, and it is mostly great. I am expecting a little more from its PBP mode. Currently, it can only do two 27" PBP. On the U3818DW, at least on your product page, it shows this:

It seems that laptop is in 5:9 ratio picture, and desktop is in 16:9 ration picture, so together they are 21:9 ratio. 

Is there anyway, via a firmware to give the U4919DW similar PBP mode. I am expecting

11:9 + 21:9 PBP

21:9 + 11:9 PBP

5.5:9 + 21:9 + 5.5:9 PBP

22:9

over by side 21:9 

22:9

The last two options require three inputs.

I am requesting this because how I use this monitor. I want to play a game in full screen 21:9 mode, open a browser window for a YouTube video, another browser window for game stats web page. If I can get 11:9 + 21:9, I can stack two browser windows vertically and that is easy to do. 

Another thing may not have much to do with PBP mode. When I calibrate color on DP input, other inputs are still on factory default setting. Should it make more sense to apply brightness and contrast across all input? At least give an option like "apply color setting to [input 2].
