Multi-objects **SYMMETRIZE** function (.L / .R) like we have with Armatures, but for objects in Object Mode!!!

When rigging we can easily create the left part of the rig and symmetrize it with 'Armature --> Symmetrize' to the other side. Blender than creates flipped duplicates of the bones ending with .L and renames than to .R .

However, when in Object mode there is no such thing. While there are lots of occassions where this is needed / useful.

Please see example below: Where I would like to have the exact same tank wheels with all individual parts and the curve which they are based on, flipped-copied to the other side (Just like we can with Armature bones in edit mode with Armature --> Symmetrize).

This now is a pain to do and takes a huge amount of time as everything needs to be done by hand one by one and takes several actions per piece to do.

Please dear Blender add a multi-select Symmetrize function in Object mode, just like we are familiar with in Armatures!

For at least meshes and curves!
