We used to do that but not anymore. The reason is that if your P/L is not at or aft of disk your nose gear will be subjected to undue stresses.
Just towing a Dash places undue stresses on the nosewheel. The structure is very weak around the nose leg. Fine for flying, taxying, landing loads but towing and pushing back when full is not a good thing.
