In that case. There many ways to solve this. I have 2 options for you.
Option-1 - Create 2 scripts. First script will create family in the base which is hosted to the family in the linked model and remove the “Imported Instances” that was hosted and finally stores “ElementID” in excel file to move the elements.
Second script will read the ID’s of the elements and then use “SpringsElement.SetLocation” node to move the location of the families according to the host of the linked model family.
Option-2 - Use “Springs.Collector.LinkedInstanceElements” to refresh True/False Boolean to Get locations of family from linked model and set the modified location.
And here is GIF in action:
The choice is yours 
Good Luck!
