Change permissions

We using kanboard for something little different than Projektmanagement. We would like to use it as a system to define your values an sort theme in swim lane according to there priority

Is it possible to reduce permissions, so that the title, tags and description can not be changed bei an user. Only admin and manager can change.
But it should remain possible the the card is moved to other swimlanes.

Is there a ugin to control the permissions or is it possible to have a role like a reduced user.

Thanks for answers.

You can try by defining custom roles in the project settings.
