I asked ASUS to implement this feature in their firmware:

(scroll thru the comments - mine are under the same name is hear). If anyone who is using/interested in this feature adds their support to my request on that forum, maybeASUS will listen to us and will implement it... keeping fingers crossed (Merlin, if they decide to do that, please help them to get it done right )
P.S. Obviously, if ASUS implements it, Merlin's firmware automatically will get it too.
