Is it possible to pre-load WMS connections for a map in kibana.yml?

I'm designing an implementation of the ELK stack for deployment with Docker and I would like to have Kibana installed with a map already present on login - ideally with some provided WMS layers added to the interface. I know there is a map.tilemap.url option available but I get the impression that is only for assigning a basemap from a Tile Service. Is there a way to add additional spatial layers through config? Thanks!
