I presume you are referring to DX Spots on the panorama. See your MB1 user manual, section 5.12 to have ESDR2 generate and post. So for the basic Spot display you do not need other software providing you only want DX Cluster Spots.
Additional 3rd party software will achieve the same at least with also, for contests and an appropriate TCI enabled logger, colors to differentiate between mult, new band, dupe, etc.
SDC Skimmer, or the Afreet CW Skimmer, will add locally heard Spots to your panorama.
