Need to add the SQL Request control that is in the on-premises version to Nintex Forms for O365

This functionality exists in the SharePoint on premises product, and we need the same functionality to migrate an existing form to SharePoint Online. The form needs access to our customer data and this dataset is too large to keep in a SharePoint list. We also need to be able to use the Nintex Gateway to create the connection as this database is inside our corporate network. In order to migrate from one environment to another, there needs to be feature parity.
