Change Material Properties in Generative Structural Analysis Workbench

I'm unable to view or edit the properties of materials assigned to parts in the Generative Structural Analysis Workbench. If anyone can advise me on how to do this, I would appreciate it.

If links to the screenshots are inoperative, please notify me and I will try to fix them. Note: I'm using CATIA V5R23.

Thank you.

SECOND EDIT:

I answered my own question. After right clicking on the material, in this case Aluminum, associated with the part undergoing analysis, I was able to edit material properties under the Analysis tab. See link to screenshot below.

I now need to determine how to change the units of Young's Modulus, etc. so that all units are English and not metric. My preference is to work in all English or all metric, not a mix of the two.

If you do it in SR1 I can't help you, but you can do it as regular parts and Structural Analysis would work even with a beam mesher. However, for designing frame structure you have to use something else than Structural Design, try https://www.youtube.com/watch?v=tcZ8MgQLD40
