Issue: Unable to send Identity Traits values when creating a registration flow

I am using Ory’s Account Experience ( hosted UI )
I have newsletter optin: bool ( default to true) in my Identity schema
Upon registration flow creation, I want to check from CloudFlare Header is country is IN LIST, and IF YES, then I want the newsletter optin: false
I tried sending this data with the registration flow in creation ,but none of the solution below worked.

/self-service/registration/browser?newsletter=false
/self-service/registration/browser?traits.newsletter=false
/self-service/registration/browser?prefill.newsletter=no
/self-service/registration/browser?traits={newsletter:false}

Describe your ideal solution

Ideal Solution

Just the way we can send return_to param via user registration flow creation query, we should be possible to send some default/desired trait values. Ideally ability for our app to send certain data during the flow generation via url that currently we handle via API.

This applies to all flows

• registration
• login
• etc....

This is what currently works
/self-service/registration/browser?return_to="xyz.com/x/y

This is what would be REALLY nice to have
/self-service/registration/browser?return_to="xyz.com/x/y&traits.newsletter=true&trait.x.y="abcd

Workarounds or alternatives

Currently only work around is to change the feature's flow

We let user register simply with newsletter = false
Upon registration when user is redirected to the app's domain, this is when we trigger a dialog box and let user make some trait selections

Upon trait selection submission, we make Ory API call to update those selections
