I've seen floor pumps with a tank to seat tubeless tires -I actually own the Bontrager one. But never a handump.
If you ride tubeless, you take a tube with you and use it if you get a flat. Then when you are back home you try to fix the tire and reseat it. Some times you may be able to field fix a flat if you didn't unseat the tire. But most often, you just put a tube in it.
If you are dead-set on trying to field seat tubeless tires CO2 cartridges (The big ones) are your best option.
