Keeping previous categories while dragging and dropping?

{"ops":[{"insert":"Hello! Maybe I missed it, but is there a way to keep existing catagories when dragging and dropping cards into new catagories? \n\nFor example, if I drag a card from the default \"Sorcery\" category into the \"Ramp\" category, the card now only has the \"Ramp\" catagory tag. What would be ideal is if I could drag a card from one catagory to another, having it keep the previous categories while staring the new catagory.\n\nMight not be what everyone is looking for, but maybe there's a setting somewhere that I missed?\n\nThanks!\n"}]}
