At the moment there's a good chance that questions about DSM 7 will be asked, but not everyone that can help will have migrated to DSM 7. @SynoMan has added the DSM version tag for thread subjects: hopefully people will be using this when asking for help.
In general the solution will probably be the same as it is for DSM 6 but how to get to where to do it may have changed. In case people aren't aware, Synology has updated their Help pages and you can now see the Help that is specific to DSM version.
