The BOM in a shop drawing will show only the pieces (MP or SP) which are really in the drawing. When the drawing is created it will have directly the dimension from the model. For example let's take the column table from the attached pdf. In the model you have to model all the pieces marks from E1C to W12C, when the drawings will be generated E1C it will get a drawing with the dimension 25'-8" not A or 13'-5" not B. Same thing for all the other pieces, they will get a separate drawing.
You can’t put in the BOM elements which are not in the model; once you model them because they are different you can’t have the same drawing for.
We hope that this will answer your question. If you have any further questions, please don’t hesitate to contact us.
