Question about softbodies

Ok lets say i create a plane, make it a softbody, and press alt-A and have it fall and collide with a cube below it. Is there a way to pause this on a certain frame, where it looks the way i want it, and keep the object in that shape? Whenever i go to edit it, it reverts back to the origanal plane. Hope this makes sense. Any help would be great. thanks

Go to the frame you want. Hit “Apply” button in the modifier.
