What is a way for customers' information to be attached to time sheet entrie

What is a way for customers' information to be attached to services rendered / time sheet entries? This  will then facilitate invoicing the relevant customer.

Our need is to generate  one invoice for a common activity like SUPPORT delivered to different Clients over the same date range? E.g.

 1.       Support delivered to ABC Corp.

a.       6 hours on 03 Nov 2010

b.      2 hours on 04 Nov 2010

2.       Support delivered to PQR Corp.

a.       3 hours on 03 Nov 2010

b.      5 hours on 04 Nov 2010

c.       2 hours on 05 Nov 2010

d.      2 hours on 06 Nov 2010

 Is  this possible to be done using  Zoho Project Time Sheet and Zoho Invoice?
