Hi there,
I think what you want is to create a customized expression, which is a function of several variables. Though it is up to you to define the relationship between your expression and each of the referenced variables, note that you can create a reference to any of LEAP variables (not only Key Assumptions). Please review this help page:

Using the keyboard combination Ctrl-B, while typing an expression, will bring up a menu in LEAP which allows you to select a branch and then select a variable located at that branch, to which you want to create a reference.
Hope this helps,
Taylor
