Option to input load values in STAAD as a function F(x) where x varies ( e.g x= depth)

In recent times, I have been designing a large number of buried underground structures. (I figured many Engineers may have similar experiences on this too).

For buried structures, a few of the applied loads are a function of a single variable i.e. depth below ground. I was wondering if it is possible to introduce a custom (or user defined) Load function that is driven by an equation i.e F(x ) such that "x" is a variable such as depth.

Note: This feature could also have options for multi-variate load function i.e Applied load L = F(x, y) . That function will be up to the engineer/user to carefully create and define in STAAD Pro .

Hence, all the applied load values that will be entered into relevant Load cases/ load items can all be changed automatically when the dependent variable(s) "x" is changed by the user. For example, this feature will help to automate the repetitive tasks of needing to input "fixed load values" in each of the load cases for every change in depth "x".

I think this feature would help speed up the process of updating lots of " fixed load values" real quickly when multiple depths are to be analyzed for a variety of structures. The STAAD file can be saved and the variable "x" updated. New load values will be auto-updated based on "x" for all relevant Load cases with the function.

In addition, this equation F(x) driven by "x" load values can be suitable for other applications such as quick revision of hydrostatic/ earth pressures at various depths

Thank you
