The displayed Via Current is not a maximum rather a recommendation to keep the temperature under control. A rise of 20° to 30° in temperature is usally fine, but it depends on your application.

If you have the space to integrate multiple vias in parallel, go for it! I would suggest going with conservative values of 500mA per via for a 10° rise or using even bigger vias if your manufacture allows it.

Here is a tool for calculating temperature depending on via parameters.
