I have used so called "monkey patching" to achieve something like this
(in fact "function call tracing").
"monkey patching" means code modification at runtime.

Suppose your application implements a logging decorator `log`.
Then on import, you can replace methods (easiest) or functions
with decorated variants either directly in the imported module/class
or for use by the importer.
