Is it possible to wildcard watched kubernetes namespaces?

Is it possible to wildcard, or apply regex filter, to watched kubernetes namespaces? I operate multiple traefik deployments in a cluster and would like for these to auto watch new namespaces introduced that follow a particular naming pattern, like so:

--providers.kubernetescrd.namespaces=app-a-*
--providers.kubernetesingress.namespaces=app-a-*
