I don't think this is a true statement. WD hitches do not change the tongue weight. They just redistribute that tongue weight among the available axles. If your tongue weight is 1400 pounds with a regular hitch it will still be 1400 pounds with a WD hitch. It will just be carried by different axles but there will still be 1400 pounds on the ball.
The only solution to the OP's problem is to move some weight further back in the trailer or move the trailer axle further forward.
I could be wrong but I don't think so.
If weight is moved to the axles, it must come off the hitch. In other words, the total weight of the vehicle and trailer do not change so if you move some of the weight to an axle, it must be reduced from the hitch.
One of the things that a WDH does is reduce the torque on the receiver. That is why receivers are rated for higher loads when you use a WDH.
The following is a simple illustration.

That, however does not mean that the weight did not transfer. It just means that as the weight is added to the drive axle, air is added to the rear air bags to compensate.
