Setting IngressRoute route field with a common value for multiple ingress routes

Traefik Traefik v2

I have multiple IngressRoute definitions with the same match field, is there any way I can set this value from a common place like a ConfigMap?

apiVersion: traefik.containo.us/v1alpha1
kind: IngressRoute
metadata:
  name: my-ingress
spec:
  entryPoints:
    - websecure
  routes:
  - match: Host(`my-site.com`) && PathPrefix(`/grafana`)
    kind: Rule
    services:
    - name: my-grafana
      port: 3000
