Best UX to Indicate To User That They Can Submit Multiple Times

I have a basic form template as follows:

The user enters data and then saves the data. The user potentially has a number of these submissions to make.

What is the best way to indicate to the user that they can add another entry?

Should the button be renamed to "Save and add another" or do I redirect them away from this page and to their dashboard (which is where they came from in the first place) where there is a link to "Add another entry". Clicking on that link brings them to this form again, so in effect they are going back and forth from the dashboard to this form if they have a number of submissions to make.

What design would involve least effort for the user and also most intuitive for the user?

Thanks.
