Skinning Editor: Create parent bone

Hi. In Skinning Editor i already created skeleton for my sprite (hands and legs) and too late i realized that i need these separate parts to be children of another part (body). Is it possible to create new bone as parent of existing bone or I need to create entire skeleton all over again?

there is a button name visibility on top right of skinning editor, click it and you will say thanks to me. i won’t tell you that i was an idiot who took 3 years to discover that.,[199514-360截图176709069893121.jpg|199514]
