WP ToolKit default set

Hello, as a web-hosting provider with custom WordPress package of plugins/themes sets, I would like to be able to change the default plugin/theme sets from 'None' to any of the available on the list when using the WP Toolkit, so that our customers could take advantage of our custom set without the need to select it from the drop-down menu.

We've noticed a lot of them don't initially select it because they will just fill their intended domain for the website and click 'Install'. This way any new installations would always be setup with the custom set and it would make it easier and simpler for our customers.
