The costume property for the rig still appears even if the rig is in pose mode

It would be helpful if the prop costumes for the rig still appeared when the rig was in pose mode. Users can add rig settings such as IK/FK by creating custom properties and driving them. Unfortunately for now, whenever the rig is in pose mode, the property doesn't appear, only the selected bone property costume appears. I hope the rig property costume also appears
