Add customisable proxy application settings to self service

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.
