Robot_Toolkit - Bar Stiffness Modifier Request

We have a process for editing the stiffness matrix of panels, but it would be great to have one to change the stiffness of bars in Robot.

This falls under editing the Ix, Iy and Iz values of the bars.
(Ive uploaded a basic grasshopper script in the following link : https://burohappold.sharepoint.com/sites/BHoM/02_Current/Forms/AllItems.aspx?viewid=a5a93cba%2Dfcca%2D46cc%2Da31a%2D80b8d5cbfd7b&id=%2Fsites%2FBHoM%2F02%5FCurrent%2F12%5FScripts%2F01%5FTest%20Scripts%2FRobot%5FToolkit%2FIssues)

Start by finding the existing process for editing panel stiffness in Robot_Toolkit and review the linked Grasshopper script for the requested workflow. Done means providing an equivalent process for bars that edits their Ix, Iy, and Iz stiffness values in Robot.
