FA has plugin extensions capability. All extensions are loaded in from the Default Company and can be activated for any or all of the companies in that FA instance.
A list of extensions are in my repo. All official extensions are available for installation from within the default Company login in FA in the Setup tab.
In your case, you will need to make an extension for your workflow or have someone make it for you by posting a bounty in the Job Offers board.
Search the Wiki and the Forum before posting though.
