No you can't : Treasure terrace hold only 5 golds (unless you bought it before oct.2013 : those ones hold 10 golds)
So you have to collect twice a day if you want your 10 golds
But if you have only 2 golds dragons you can buy 2 Treasure terrace (sometimes they are on sales) and put 1 in each : you need then to collect once a day to get your 10 golds
Btw you can't have 2 Treasure dragons : we are limited to one of each golds dragons (Treasure, Goldleaf, gilded, midas, stainglass, sterling, forbidden and goldwin)
And we are limited to 4 Treasure terraces.
