BOM Column that calls out component sheet

Hello Community, relatively new to the forum.  I have been struggling with creating a custom BOM report.  I feel like I am close.  I am trying to create a report that calls out the symbol column and page number.  I am using the page number from the document book tree.  I figured out the formula to callout the column which is sym_columnmark.  I have not figured out how to call out the sheet number just yet.  I found fil_tagposition which does not help.

 

Any assistance will be greatly appreciated.

 

Thanks,
