Consolidation of Requisitions initiated from Project Contract

 Hi,

I am initiating requisitions from Project Contracts module from different contracts and for different projects. In this case can single requisition be generated consolidating requirements of all projects?

eg.

I have two Project Contracts and projects attached to it say ;

Contract no 1 and corresponding project no 1

contract no 2 and corresponding project no 2

Now I initiate requisition for project 1 from contract 1 for say X item and quantity is 10. Similarly I initiate requisition from contract 2 for project 2 for same X item and quantity 20. Now for this can single requisition be generated in purchasing module with quantity 30?

Regards
