I need to add more cities

First of all, your plugin has been helpful over the years. Thank you very much.

Now, I need to add more cities particularly to Lagos, Nigeria. I suggest that there should be a way users can add and/or remove cities they want.

For instance, below are the current cities in Lagos, Nigeria, and the desired cities that I now need respectively:

    'NGLAAG' => 'Agege',

? ? 'NGLAAI' => 'Ajeromi-Ifelodun',

? ? 'NGLAAL' => 'Alimosho',

? ? 'NGLAAO' => 'Amuwo-Odofin',

? ? 'NGLAAP' => 'Apapa',

? ? 'NGLABA' => 'Badagry',

? ? 'NGLAEO' => 'Eti-Osa',

? ? 'NGLAEP' => 'Epe',

? ? 'NGLAID' => 'Ikorodu',

? ? 'NGLAII' => 'Ifako-Ijaye',

? ? 'NGLAIJ' => 'Ikeja',

? ? 'NGLAIL' => 'Ibeju/Lekki',

? ? 'NGLAKO' => 'Kosofe',

? ? 'NGLALI' => 'Lagos Island',

? ? 'NGLALM' => 'Lagos Mainland',

? ? 'NGLAMU' => 'Mushin',

? ? 'NGLAOI' => 'Oshodi-Isolo',

? ? 'NGLAOJ' => 'Ojo',

? ? 'NGLASH' => 'Shomolu',

? ? 'NGLASU' => 'Surulere',

'NGLAAG' => 'Agege',
'NGLAAI' => 'Ajeromi-Ifelodun',
'NGLAAL' => 'Alimosho',
'NGLAAO' => 'Amuwo-Odofin',
'NGLAAP' => 'Apapa',
'NGLABA' => 'Badagry',
'NGLACV' => 'Chevron',
'NGLAED' => 'Egbeda',
'NGLAEO' => 'Eti-Osa',
'NGLAEP' => 'Epe',
'NGLAID' => 'Ikorodu',
'NGLAII' => 'Ifako-Ijaye',
'NGLAIJ' => 'Ikeja',
'NGLAIL' => 'Ibeju/Lekki',
'NGLAIY' => 'Ikoyi',
'NGLAKO' => 'Kosofe',
'NGLALI' => 'Lagos Island',
'NGLALM' => 'Lagos Mainland',
'NGLAML' => 'Maryland',
'NGLAMO' => 'Magodo',
'NGLAMU' => 'Mushin',
'NGLAOD' => 'Ogudu',
'NGLAOI' => 'Oshodi-Isolo',
'NGLAOJ' => 'Ojo',
'NGLAST' => 'Sangotedo',
'NGLASH' => 'Shomolu',
'NGLASU' => 'Surulere',
'NGLAVI' => 'Victoria Island',
'NGLAYB' => 'Yaba',

I humbly ask that you help update these newly added cities as I need them urgently.

Also, kindly help create access to add new cities from the dashboard in your future update.

Thank you very much once again as I look forward to your kind assistance.
