Store Extra Lives

I don't know if this Idea has been mentioned before. The Ask for Lives feature has not been working properly for some time. At times you are lucky to receive one life all day, and other times you receive five at once when you may only need two in order to fill your max lives back up. You end up collecting all five of these lives and essentially wasting the other three. In these instances, it would be nice to be able to collect all the lives and "store" the extra ones for later use.
