Elemental Adept feat macro?

Hello, im trying to figure out how to perform the function of a feat automatically using roll20 macros. The feat reads as follows: "...when you roll damage for a spell... you can treat any 1 on the damage dice as a 2" So essentially, its like performing the ro function (IE: 2d6ro<2) but instead of rerolling the dice, it just needs to make it a flat 2. I cant figure out how to do this via roll20 macros. is it possible?

You would need to use the kh1 function. {2d6,4}kh  Just use the second number as the lowest roll possible, in this case the number of d6s x 2 and it should work out. edit: See below, they need to be broken out for each die. 

It's possible to do this using the keep/drop function . e.g. Fireball: [8d6] {1d6,0d0+2}k1 + {1d6,0d0+2}k1 + {1d6,0d0+2}k1 + {1d6,0d0+2}k1 + {1d6,0d0+2}k1 + {1d6,0d0+2}k1 + {1d6,0d0+2}k1 + {1d6,0d0+2}k1
