Is there a way to draw a line at a certain station and offset within the referenced profile view in ORD?

My alignment are profile are in ALGNRD01 file. I referenced my alignment file into a different .dgn file called MOTIF

In the MOTIF file I opened the profile view of the alignment and I am trying to draw a line at certain station offset. 

I understand that I can do it in the ALGNRD01 file and it will show up in the reference. In this case I do not have access to the alignment file. I want to know if I can can somehow draw a line (or at least a data point) at a certain station offset within the referenced profile view within the MOTIF file. 

Thank you.
