Doubts for Xgenerative design

Dear all,

 

I am facing an issue with the naming of the published geometries. After completing the algorithm, I publish a set of Axis points, Axis systems, lines for length, and Height for a set of facade panels. These become as inputs for the UDF that we have created to instantiate. 

Doubt one - Can we publish dimensions instead of lines? I couldn't find a way to do so

Doubt 2 - I changed the names of my published geometrical sets but it doesn't reflect in the tree. Please see the picture below

Doubt 3 - I am using Xgenerative design. Can I create more than one design sequence inside the same 3D shape?
