I need CO Lines be programmed to be answered by hunt group on a Mics or CICS...is that possible?

Yes it is possible.
Read the System Coordinator guide for best choices under hunt groups.

You can have Auto Attendant answer lines and have an option in CCR to point to a hunt group as well.

Set up Table with CCR.
Instead of a CCR MENU make it a CCR Transfer to extension.
Make the extension number the hunt group number.
