Scion's Keeps and Divine Grace Stone - Can we have them one by one instead of a bundle?

[Kozuki]

SK boss always drops grace stones in bundle of 2-3. This makes people who only needs one single more stone to pay extra gold for one-two more that they don't need, and waste the chance of other people who also need them.

 

I think the stones should just drop separately, 1-1 or 1-1-1.
