Can I automate the Passwords app to copy all passwords into a specified shared group?

I was so excited to get the Passwords app now that it can share passwords with a family member via a shared group.

However, in order to share a new password I have realised that I need to manually move it into that group on a per password basis?

Would it be possible to solve this by automating the copy of all passwords (or looking ahead, select by criteria) into that group either a) on a trigger such as creation, or b) regularly?
