Hue sub workflow

I have eight workflows and I want to put them in one workflow.So, I have used sub workflow in my allworkflow(this workflow contains all my eight workflows). My eight workflows have dynamic parameters like the picture shows,but the sub workflow does not have any place to set these dynamic parameters,and when I start the allworkflow it will failed and the log shows variable [start_day] cannot be resolved.
So,the problem is:I want to use sub workflow,but my workflows have dynamic parameters and sub workflow does not have any place to set these parameters.Is there any solution to solve this?
