The following is a link to a code that allows you to make several configuration savings, which you can load anytime as long as you don't clear your cookies.
I would like to know if it's possible to make a radiobutton, that displays a list of all the stored names.

The link:

If you remove a configuration, the radio button goes away, as well.

Saving a configuration will add a radio button for that configuration at that time

You can add as many configurations as you would like.

Just select a new radio to change to a different configuration.
