Get translations from server

Hello, I’m using ngx-translate for translations. File json is stored in /assets/i18n/lang.json
My question is, can I upload this file dynamically? What I am looking for is to load the file from the server, to add languages from the server without having to send an update of the ionic application.
If you use the setTranslations method, this method does not store translations on the device, if I quit my application and re-enter translations are deleted.
