Unless the tech deployed in system is uploaded to all colonies with research facilities in that system or it is uploaded only to the nearest one such colony, I fear it will be uploaded to the bad colony.
No, I unchecked that "don't upload tech" checkbox while parked at a smaller colony with just 1 research facility while there was another bigger colony with 4 facilities. All stored data went to the bigger colony. Reload time.
In the meantime I have collected both armor and sensor techs salvaged techs at one ship so I guess I could only deliver those to Earth where the most facilities still are, to get use of all those points../.
Last resort: SM-edit away all labs on one colony, unload tech data, edit labs back in.
Yes, in the end, noting there is that anomaly bonus of 90% to sensors on that small colony, I just forfeited those armor tech points and used SM to make sure all those salvaged techs go to this smaller colony.
