Custom URL's

[abrombo]

How can I add a custom url that will be remembered from session to session. The only service that I use that is predefined is "Amazon Prime Video." The other two services I use are "MHz Choice" and "PBS Passport" with URL's -

https://mhzchoice.com/

https://www.pbs.org/passport/videos/

Is there a way to add them and their icons to the electronplayer menu?
