Account > Website field prepended with http://

The http:// is being applied by the URL field in clients/base/fields/url/url.js. You can simply type in the https:// in the front.

   format:function(value){
        if (value) {
            if (!value.match(/^([a-zA-Z]+):/)) {
                value = 'http://' + value;
            }
            let whiteList = app.config.allowedLinkSchemes;
            this.def.isClickable = true;
            if (!whiteList.filter(function(scheme) {
                return value.toLowerCase().indexOf(scheme + ':') === 0;
            }).length) {
                this.def.isClickable = false;
            }
        }
        return value;
    },

If you want https:// you can work with a developer to create a custom version of the url.js that overrides the format function and replaces the http:// with https://

cheers for the info Jeff Bickart

Luke Ridgway am on it and will build into next accounts module update

Jeff Bickart, Thank you for the info...  don't think I could see the wood for the trees!  

There are other ways to accomplish the same thing. You can use a LogicHook, it may be possible to use a SugarBPM (no programming) as well.
