Welcome to the Forums @SunsetRunner!
In this case you are correct in that it is only a one-way sync. Maybe you could try getting in touch with Weight Watchers directly and ask for a two way connection like this. Do keep in mind that these integrations are developed by the third-parties and so they should be able to alter it and change the way in which it syncs.
Let me know if you have any further questions.
