Pimcore Route Error

What i want to do is to redirect to custom exportProcessUrl rather than that of pimcore url i.e /admin/object-helper/do-export.

I changed it in the web/bundles/pimcoreadmin/js/pimcore/object/helpers/gridTabAbstract.js file but in further updates my changed file may get replaced by further update.

How do i tackle it???

Copy the file to your AppBundle into AppBundle/Resources/public/pimcore/js/gridTabAbstract.js. In there you simple extend the class you want to modify.

After that you will need to include the new JS file via your AppBundle, which should implement the PimcoreBundleInterface
