Add Custom URLs to New Tabs Dropdown in Home Settings

[S3NTYN3L]

Is your feature request related to a problem? Please describe.
I dislike having to install the New Tab Override extension just to get a homepage loading when opening a new tab.

Describe the solution you'd like
1 - Consider adding a Custom URL... option to the Settings > Home > New Windows and Tabs > New tabs drop-down.
2 - Also consider adding a Current Homepage option to that same drop-down. This option would pull the URL appearing in the Homepage and new windows field. Or, perhaps, it can be made to pull any URL from the delimited list if the user has multiple homepages.

Describe alternatives you've considered
As above. I'm already using the New Tab Override extension to accomplish this, but it really seems unnecessary when this functionality could have been built-in from the start.
Besides, the extension doesn't allow for choosing a URL from the delimited list as this might if approved and implemented.
