Rename multiple objects in Outliner Is it possible to rename large groups of related objects using a "replace" type capability?

There doesn't appear to be anything in the add-ons for this.

I'd like to be able to add prefixes/suffixes or change a specific characters form "A" to "B".

Thanx in advance for any help.
You can Batch Rename objects in the Outliner (since 2.81)
Shortcut: Ctrl + F2
