How to Add to Vagrant Settings From Loaded Vagrantfile

How can I add to an array from a loaded Vagrantfile?

I can override the setting, but if I try to add to the array, I get an error. Here is the loaded Vagrantfile. The filename is Vagrantfile.general

# -*- mode: ruby -*-
# vi: set ft=ruby :
Vagrant.configure('2') do |config|
  config.vm.provider 'cloud_service' do |cs|
    cs.tags = ['ExampleTag1']
  end
end

Here is the Vagrantfile that loads the above:

load 'Vagrantfile.general'

Vagrant.configure('2') do |config|
  config.vm.provider 'cloud_service' do |cs|
    cs.tags << 'ExampleTag2'
  end
end

Here is the error:

Message: NoMethodError: undefined method `<<' for :__UNSET__VALUE__:Symbol

Here is a workaround, but this is not a good way to do it:

load 'Vagrantfile.general'

Vagrant.configure('2') do |config|
  config.vm.provider 'cloud_service' do |cs|
    cs.tags = ['ExampleTag1', 'ExampleTag2']
  end
end

Here is one more workaround, but it doesn’t access the array set in the object created by the first Vagrantfile. It uses a Ruby global variable set in the first file and operated on that global variable in the second Vagrantfile.

# -*- mode: ruby -*-
# vi: set ft=ruby :
$cs_tags = ['ExampleTag1']

Vagrant.configure('2') do |config|
  config.vm.provider 'cloud_service' do |cs|
    cs.tags = $cs_tags
  end
end

load 'Vagrantfile.general'
$cs_tags << 'ExampleTag2'

Vagrant.configure('2') do |config|
  config.vm.provider 'cloud_service' do |cs|
    cs.tags = $cs_tags
  end
end

I still would like to know if it is possible to access and change the array in the Vagrant object created by the fist Vagrantfile.
