FedEx dimensional shipping options

Is there a way to have FedEx’s api in Magento 2 utilize volumetric (dimensional) shipping over weight? My FedEx account is set up as such, but when checking out it’s completely undercharging and only utilizing one box vice the required amount of boxes to fit the order.

Is the only option to create a new module or find an extension?

Can adding attributes to each product accomplish this? I see there’s a weight, but I believe the LxWxH option went away with the temando shipping.

Any advice will help.

Thanks
