[otrs] Customer Permission

Good morning dear all, does anyone know how to add more permissions to customer? The default configuration suppose only two kind for customer ro and rw. I'd like to add createpermission to force customers to create all theirs tickets in one queue, but to be able edit them in other queue (after they moved there by agent).
