Update all instances of a imported model

If I import an object and place multiple copies in a project eg. a plant. how do I update them all when the source model has changed?

This might be due to an issue I’m having with duplicating models. If I hold Shift + Coordinate Axis then it makes a copy not a duplicate. Is this a bug or by design? I often use the shift method to duplicate as I want it on the same axis.

Hi
If you need to update multiple copies or duplicates at the same time, you can select them all at once in the object list and then right-click to choose the option to reload or replace.
