ChaRM: approving of a change request by various list of end users

Dear, experts.

Can I customize ChaRM so, that before initiating change request a support message should be approved by by various list of end users depending on component (component A - list 1, component B - list 2)?

For example some end-user wants to change established business-process. In this process are involved other end-users, so to trigger changes he have to ensure that other end-users are agree.

can you suggest any profitable solution?

thanks in advance
