Hi,

Is there anyway to use a formula along with variable expansions?
This makes life much easier as I can set up a single setup file in the root and change it for different runs rather than changing similar parameters in multiple files.

For example assume I want to sample multiple points as fractions of a channel length, now changing the channel length makes me update all the points, while if I had the luxury of formulas in variable expansion I could have simply had the points dictionary as:

(1*$xm/10 0 0)
(3*$xm/10 0 0)
(5*$xm/10 0 0)
(7*$xm/10 0 0)
(9*$xm/10 0 0)
