How to include data from workflow input into activity logger as child parameters - to be printed in each log

using typescript SDK -
in temporal I wish to add a logger inside activities such that - as child parameter to that logger I should be able to add, any data available in workflow input
so assume my workflow A calls activity B, assume a parameter P was passed as workflow input to A when it was started , I want to print this parameter P in every log in activity B.
my limitation is that - I cannot pass parameter P as arguments to activity B everytime since its too cumborsome and sort of ruins the design of function args.

so overall - when calling activity inside workflow I do not wish to manually pass all logging parameters everytime. consider the worklow start below

                temporalClient.startWorkflow(
                    myWorkflow,
                    [{message: "greeting"}], //this can have a lot data , I want to add this message to each log in activity
                    TASK_QUEUE,
                    workflowId,
                    searchAttributes
                );

now consider workflow definition and call to activity below

export async function myWorkflow(wfInput: {message: string} ) {
        callActivity();
    } catch (error) {
       
    }
}

 function callActivity () {
     const { logger } = getContext();
      logger.info({
            message: "activity started",
        });
  }

export interface ContextWithLogger extends Context {
    logger: Logger;
}

export function getContext(): ContextWithLogger {
    return Context.current() as ContextWithLogger;
}

how do i accomplish getting the parameter message inside every log of callActivity by default

It doesn’t do exactly this but you can modify it for your use case.
