Currently, RAM can design "Joists" but doesn't specifically design the members of the joist.

As a joist designer, we would love to be able to design the sections of a joist per SJI
(Double angles, webs, etc)

This can be implemented by Bentley, or Bentley should develop a method for users to create custom design codes which can add additional checks compared to another already made code OR remove code checks required by other code checks.
