Customized mhtml and excel output

Hi,

BO Version: 4.1 SP6

We have a particular business requirement, where we have created a publication to send automated email to the business with excel and mhtml embedded report output. However, the issue is that the business wants mhtml to have only selected few KPI rows visible and excel to have all KPIs displayed within the same email body / attachment respectively. Is it technically possible in SAP BO (Webi).

Please help.

Thanks!
