Adding a PI to an OR alignment that was offset from a survey alignment

I created an office alignment by offsetting a survey alignment.  When I made it I thought I had it setup the way I needed it; however, now I need to add a PI that is not in the survey alignment.  How would I insert a PI in my office alignment?  I tried the Microstation tool to insert a vertex but that doesn't allow me to select my office alignment.  

I also have two associated profiles to my office alignment, existing and proposed.  

Any help would be appreciated!  Thanks in advance!
