Enterprise Contracts with its Corporations

I may be missing something here but I am not finding a way to contract between my corporations in my Enterprise so they can supply each other.

It is also on the trading page.

There are so many variations and possible trades, I am not sure which ones you cannot find, or are impossible.

Please check and then explain clearly what you want to do.

Hi Andy, looked at both locations and found neither will help me accomplish what I need to do.

As an Enterprise I want to supply my Enterprise Companies not some other country's companies (this is what you can only do when playing an enterprise) - If I was playing my Country this is easily accomplished with contract between the two country companies, but you cannot do this between Enterprise companies or at least I cannot find the way to do it.

If it was the country where my enterprise was located and was for the country's corporation no problem, but I want to supply my own companies first to ensure they are operating at 100% which lately has
