Profile frame multiple secondary alignment within the same heading/dataline


Currently working on a project that has multiple alignment that are attached to the main corridor alignment. (ie. indented car parking bay parallel to the main alignment.) 

What Im wanting to do is with in the framed data box is to have multiple alignments for a single heading or data line. see attached screen shot.

Ive tried by adding 'insert label' which creates an additional line under original heading but when creating the frame only one alias appears and not option to have multiple as I would have hoped.

Can it be done??

The green alignments indicate the indent car parking bays which are separate alignments.
