Dynamic measure based on fields in matrix table

I have a measure doing a simple variance calculation of two numeric fields within a matrix table and then on another page I have the another matrix table with a measure doing the same calculation but with two other numeric fields.

Is it possible to use the same measure but use these new two fields or will I have to create another measure? Trying to be efficient and reduce the number of measures I create but I can quickly see myself duplicating a lot of measures if I can't find a more dynamic way of doing this.
