It would be great if the settings to add automatic proxy addresses to particular URLs could be added to self service. These are the settings as described in this support article: https://support.talis.com/hc/en-gb/articles/17338196256157-Customisable-proxy-application.
This would be particularly helpful with the management of adding the proxy to specific web addresses for different resource providers.
I've just logged in here to ask for the same - we're changing our authentication to move to a different method and it would be really helpful to be able to configure our settings to apply different prefixes for different resource providers depending on what method we need to use.
