The importer object bundle is a pimcore bundle that set the selected grid columns automatically when importing a data object.
The installation can be installed through composer.
- Run 
composer require youwe/importer-grid-settingsto receive the bundle. - Enable the bundle 
bin/console pimcore:bundle:enable ImporterObjectBundle. - Then reload the GUI of Pimcore.
 
The working is quite simple; when you are importing a CSV file, the bundle will set up the grid automatically according to the headers of the CSV you're importing.
