Short description of error
I have a large group of bones/objects that are all randomly named and numbered, now I want to go back and rename them all in order. Bone.000, Bone.001, Bone.002 etc. But changing "Bone.016" to "Bone.001" doesn't work as there is already a Bone.001, meaning I have to go find that Bone, rename it to something else, and then go back to the first bone and change it to the desired name. Or if list of objectsis starting mid-numbering, Blender will automatically start renaming my manually entered name to the start of the list. (ie. will change my manually entered name of "Bone.016" to "Bone.000".

Expected behaviour should automatically rename and increment the non-selected bone/object in favour of the bone I am manually renaming.
