Cold-Formed Steel: More Built-Up Section Options

User request:

Would it be possible to get the Box Beam option added to the wind beam section for CFS Members:

Our USA and Australia cold-formed steel calculators both offer boxes made up of two Cee sections, but only loaded about the major axis. Please let us know any additional types of built-up CFS sections you’d like to see us add!

Could you conservatively just check two or three tracks acting together in their strong direction? Box has two tracks plus one more for the base track of the shorter wall above the header.
