Instance Thresholds based on day

Current time based instance thresholds allow me to set thresholds based on time only. But what if I have diff set of instance thresholds for weekends.
In current set up I can not do that. My use case is I have diff set of instance thresholds e.g. PVS device count weekday morning vs weekend morning & similarly PVS device count weekday evening vs weekend evening. Raising feature request to add feature where one can set diff set of thresholds based on weekday vs weekend.
