How to add an ESRI Map Server as a WMS layer in JOSM?

Is it possible to add an ESRI map or feature server as a layer in JOSM.

As an example, could the Protected Areas Database maps be added?
https://gis1.usgs.gov/arcgis/rest/services/padus2_1/PublicAccess/MapServer/0

How would I format that URL to add as a WMS layer in preferences?
