Directly adding fields to json log when log has parameterized string

[Divyadarshee]

is something like this possible example:

addItem='abcd'
logger.info(f"added todo item {addItem} to the todo list")

*note: or any way of adding parametrized string log: {'name': 'app.routes.controller', 'msg': 'added todo item abcd to the todo list', 'args': (), 'levelname': 'INFO', 'levelno': 20, 'fields': {'addItem': 'abcd'}}
