Currently the global hourly demand rule only permits shift tags as attributes. It would be very useful to allow employee tags as well, like the global demand rule. So we can ensure for example, "every hour we have at least 1 employee working who can service a specific client or perform a specific task/role". Each employee would have a tag determining their eligibility to service a client or perform a specific task/role. We can't tag such attributes at shift level since any employee can cover the shifts spanning the hour.
