Any way to access JobActivator/Scope in JobFilter and replace job parameters?

Why do I need this: I'm trying to replace PerformContext-like object in my job execution method parameters. So the first thing I've encountered is: I can't get current activator scope, therefore I can't resolve the needed parameter within the scope. The second problem is: I can't find a way to replace job parameters since filterContext.BackgroundJob.Job.Args is readonly.

This is a sample which demonstrates the problem:

public void OnPerforming(PerformingContext filterContext)
        {
            var jobContextParameter = filterContext.BackgroundJob.Job.Method.GetParameters()
                .FirstOrDefault(f => f.ParameterType == typeof(IJobContext));

            if (jobContextParameter != null)
            {
                filterContext.BackgroundJob.Job.Args[0] = container.Resolve<IJobContext>();
            }
        }
