Apply default access settings to posts written in WordPress Android app

First of all, thank you for this great plugin!
I am using it on a family blog and have set the default for new posts to “Who can read = ‘Family'” (‘Family’ is one of my access areas).

This works very well as long as I use the browser to write posts. However, if I use the official WordPress Android app, new posts automatically are assigned “Who can read = ‘WordPress standard'”. I understand that it is not possible to have the post access control menues also in the app. But is there perhaps a way to apply the plugin defaults to any new post regardless the way it is published? (i.e. you are not able to select the access area in the app, but nevertheless the post is assigned the default settings defined in the plugin)
Or, as a workaround, is it possible to define ‘WordPress standard’ = ‘Family’?

Thanks in advance for your help!
