Crafting materials

I know that Dragon Age: Inquisition has been out for a few years now, but something's been bugging me and I'm sure others can agree, as far as those who still play and enjoy the game. Dragon bone is a great crafting material, but there isnt enough. There are only a set number of Dragons in the game, and the black emporium shop only has a finite amount. Can we please get a way to buy or slavage more. For example, the black emporium doesnt restock items with a finite amount. Could that be changed?
