SS3 Ditch profile design issues

Hi,
I was dealing with ditch profile design and encountered following issues: 

1) Can I assign different feature definition for each vertical alignment? Please see attached video,it looks that 
only one feature definition per one geometry is possible. It's crucial for end condition when targeting feature definition vertical.

2) Can't figure out why end condition target type "Feature definition vertical" (tried add my CL as corridor reference) 
and "Linear vertical" don't work. "Linear vertical" works only when target aliasing is defined.
