EPM Add-In to launch a custom workbook

Hi

We are on EPM v20 SP10 Patch1 and we access the EPM via Citrix.

Using EPM Add-In deployed on SAP Portal, We are trying to find a way to automatically launch a custom workbook on launch of Excel. Currently when we launch EPM Add-In, it launches Excel with EPM Add-In and SSO, but opens a blank workbook named Book1. We want to be able to launch a custom workbook.

Is there a way to launch a custom workbook when EPM launches excel?

I apologize if I'm not using the right terms to describe the issue. I am new to this. Please let me know if you need more information.

Thanks

Manoj
