How to create template for Zoho Projects Timesheet export

Timesheet in Zoho Projects is great with a lot potentials. 

I'm trying to make this automated way so that I could export timesheet in Excel format and send to clients to sign. There is only one issue - the excel exported from Zoho Projects is not style or format our company want to send to the clients. Is it possible, Zoho Projects can let users have template for timesheet export, just like customised template feature in Zoho Invoice?

If yes, how to do that? If not, if is it possible we can program and access timesheet data from Zoho?

Thanks a lot.
