Spot Collector is a component of DXLab's logging suite. It provides a way for users of the DXLabs suite to get spots into the Flex.
HRD, as you know, is a whole other thing. If you would like a tight integration between your Flex and HRD, I'd suggest that Slice Master might just be for you. It will put spots into the Flex and is able to "color" those spots with information from HRD Logbook to show their "needed status".
