How to force user to change their password on first login on RouterOS WebFig Login Page

We created Users with custom access rights for our customer. We want to force them to change their password when they first log on the RouterOS WebFig Login page.

Does this feature already exists? How can we activate this feature or can we script it?
We already have a custom index.html Branding Page, can we make a script on this page that will force our users to change their password on first logon?

Does this feature already exists?

No…
But is this really necessary ?

Mikrotik not yet support to do that, maybe it can use Mikrotik API
