Cross section rotation of multiple structural members

Hi All,

Does anyone know a way of applying a unique cross sectional rotation to a list of structural members in GC? 

The structural member node has a optional 'Rotation' input which seems to allow the input of a single angular value which is then applied to a list of members.  However, what I need is to be able to input a list of cross sectional rotations that align with a subsequent list of structural members, thus providing each member with its own unique rotation.

Currently when I input a list of data I get an error stating that the input values are invalid.

I'm sure there is a relatively simple solution out there but being new to GC I currently do not have the knowledge base to figure it out!

Thanks

Jamie
