Possible to set the smelting speed per item?

Hi,

I tryed some things but i cant get it to work to set the smelting speed per item

i managed to set the output value for metal.fragments that works, but i want only metal frags x2 and not sulfur

Speed is per furnace yet not items

Thanks for the reply :)

Can you make a update with adding items ?

And maby also a way to set different permissions ? for VIP group different speeds ?
