Incorporating BPA Interactive Preview, Print Preview in Transaction form

   Hello.

In the BPA template management, then you go to Interactive Preview for a particular external template, the last column is called the Print Preview where upon clicking on a record's preview will display a PDF preview of the invoice.

 

On the other hand, in the Transaction form where also you can view/add/edit an invoice, a button is available (if viewing a completed invoice) beside the transaction no. field to call an html preview of the invoice/transaction currently displayed.

           

Would it be possible to have the print preview functionality found in the BPA external templates management interactive preview in the Transaction form, e.g. calling it when the preview button (encircled in red in the left image above) or Zoom toolbar button (encircled in red in the right image above) is clicked?  If yes, could you please teach me on how to go about it or refer me to any documentation available on how to do this.
