AutoCAD Inventor :: Isometric Pipe Spool Drawings

I have been asked by one of my clients to provide an isometric piping diagram for a product that we have modeled/developed for them. We have already provided models, review drawings, design drawings, and fabrication drawings for this product but what they are looking for is a simple isometric pipe diagram where they can hand write their weld test data and put the material data sheet number references. I have submitted a sample of a drawing we completed with an isometric view of this piping as a full view (iso view created by IV) but they are requesting something simpler like they are used to (one-line iso pipe spool-type thing with symbols instead of modeled valves, etc.). I am embarking on a process to get them to change their standard but I was wondering what you experts thought while I am doing this (in case they refuse).

I don't want to create drawing that isn't tied to the model somehow for obvious future-revisions-parametric reasons so I was wondering what you think my options would be for keeping this all in IV (instead of just doing something seperate in AutoCAD.
