Delmia v6 - Process Flow Diagram - Report generation

Hi all, 

In manufacturing BOM (MBOM) context, After creating a manufacturing assy using a EBOM inside Delmia with a proper 'WORK PLAN' assignment with 'Resources Allocation'

My objective is to generate the report output of "Process Flow Diagram" document for my customer company, as per their desired template. I checked the output of OTB PFD generation utility for reference, Exported excel document had very basic tabular format data. 

So to get the desired template of PFD document, What are the best work around practice/ approache?

Like is it possible with custom EKL script? Otherwise Can I modify the OTB PFD export function OR reconfigure existing XML file code as per requirement? Or to create the template using 'template designer app' then to map the design/plm attributes and use this report template under work plan and do the report generation?MBOMProcess PlanningReport generationTemplate designer 

Pls suggest the best approach for this. TIA
