Create more objects of the same type

I have a DSL with some constant and variable declarations, like:

const c1 : Int
const c2 : Int

vars
  v1 : Int
  v2 : Int
  b : Bool

But I would like to have something like this:

const c1, c2 : Int

vars 
  v1, v2 : Int
  b : Bool

I couldn't find a way from the grammar to have that...What would be the solution?
