Dynanmic chat availability based on agent login

Summary

Providing chat based on agent availability vs. hours of operation

Content

Rather than driving chat availability by hours of operation/schedule, is it possible to let customers know when they're on a designated web page that chat is available when an agent logs in and changes their status to Available? We need to provide chat that is more on the fly and not tied to prescribed hours. When an agent isn't available we can direct them to other service channels. Is this something configurable with inlays or are we looking more at a customization?

Thanks!
