Rename ID on the page

[VictorKrs]

Hello, dear WWB users!

Please tell me how to rename the ID of the page elements (or rather, part of the current name of the ID).
The following is necessary: rename all page elements starting with lg_mp_protein_ ....... on lg_pp_protein_.....
I tried to use the Global Replace tool, but nothing is renamed, despite the fact that there is such an option in the Global Replace settings.

There is no option to replace the prefix of an ID
- you can replace the full name
or
- add a prefix.
