Add more vRAM amount options to vRAM Slider

It would be nice if we could have more video memory amount options in the memory slider as opposed to either 50% of RAM (automatic graphics memory) or only 2GB maximum manually assigned... Especially with DirecX 11 games requiring more video memory, some games require 4GB+ vRAM and 8GB RAM.. in this case I only have 16GB RAM in my Macbook, so only way to meet RAM requirement is by setting all 16GB RAM to VM so that I get 8GB RAM and the rest 8GB is all set as vRAM. Of course this can slow down Mac and VM since all 16GB I have is getting assigned to the VM...

 

So basically I would like more options for manually choosing vRAM such as 4GB, 6GB, 8GB etc.
