To remove it from her tasks you'll need to direct incoming calls to a CRA to give them options. If you really want to automate it, use a STAR application to route all calls to a CRA for each day that will route an option to proper Hunt Group for for that day. As an example, on Mondays, all calls go to CRA 2511 which has option 2 for Sales directed to HG 2001, which has the member order set for Monday. On Tuesdays, all calls go to CRA 2512 which has option 2 for Sales directed to HG 2002, which has the member order for Tuesday.

How automated do you want it to be?
