Three Hour Gold Shield

I would like the option to defer this and save it up until it matures into one day gold shield.

LoL, I think just no way it could be possible. You save it up. Got 1 day free. Then you use 45 gems to get another day right when the free one expired. So you got 2 days with only 45 gems, compare to 180 for 3 days. Not fair.
