Yes it is possible.
Teamcenter saves Structure manager column configuration as user preferences (more than 1 preference)
The preference suffix is usually '...ColumnPreferences'.
Once you locate the preference for the user, you could now create the same preference for group/site.
So I have created a custom column configuration and saved. Please supply me with documentation on how to export . Than I need documentation on how user is to import.
you can use preference export and import from Teamcenter UI (from the menu Tool bar --> Edit --> Options --> Filters --> Import / Export.
I have included a screen grab for your reference (Please ignore 'site' selected in the screen grab)
