Process messages- process order

i have a process order- 4 main operations with 4 phases like 10 operation, 20 phase 1, 30 operation2, 40 phase 2 etc.at each phase different mat should be issued. all phase confirmations are required. for each phase one insp parameter should be checked by operator. in this scenario, is it possible to prepare single process inst sheet or do we need to prepare different process insp sheet? pls advise how to handle this in sap?
