get response in tasker after WM_send_variable

If I send a variable from tasker to my gear s3, sometimes it is not set in the watch. I have no control about the transfer. so it would be very usefull to get a response if it is working or not.
another usefull thing could be an extension in the tasker plugin to have a WM_get_variable.
Then I'm able to send a time to watch and then get it back and compare.
