'Scalability' has a lower priority than 'Console': is there any way to reset this priority?

Hi, I’ve done in UMG a menu to change graphic settings, it is possible to choose one of the 4 scalability, and then I apply it with the console command node (“scalability x [0-3]”), this works really well, but it is also possible to change specific settings, for example shadows, in this case I use the commmand “sg.shadowquality x [0-3]”, and here comes the problem, if I try again to use “scalability x”, it change everything exept the shadows, and in the output log I got a yellow warning that says “Warning: Console variable ‘sg.ShadowQuality’ wasn’t set (‘Scalability’ has a lower priority than ‘Console’)”, this warning can be resolved by resetting the engine, or the game but this is messy, is there any way to reset this thing in runtime? (Sorry for my english)
