EDCopilot does exobiology, too. It knows the distances to the next sample and even informs you if you leave/enter the diversity perimeter of your previous scan(s).I'm not sure if EDCopilot does similar stuff.
If you come across other species while searching for a specimen to scan next, you can scan the other species with your comp scanner and return to the nearest scanned one once you have completed the other scan.
In systems that have already been combed through by other commanders, it can even lead you to the reported scan places without having you to DSS the planet first.
