Exporting macro along with data - BEx web

Hi,

I have to send BEx web data along with a macro. The purpose is every report user down loads in his desktop gets an unique macro along with the data. The user can later use that macro for further analysis of the downloaded data.

I was reading through the How to Use Web Printing with Microsoft Excel document which details about various objects such as Packages and ABAP classes. The ABAP class ZCL_RSR_XLS_ITEM_TEMPLATE contains methods such as SET_ITEM,RENDER_DATA,LOAD_TEMPLATE_FROM_DB,GET_TEMPLATE...etc. My question is whether these class and mehtods can it be enhanced to include a macro ???

Any suggestions is eagerly awaited,

Regs
