Multiple bosses in org chart

So I have been working on the org chart(static) and I have data to add dynamically through 3rd party which I have done but I have a one thing yet to solve which is multiple bosses of a node. I have a single object(array) coming through an external app( My nodeDataArray equals to an array I have populated and I don’t want to change the structure too. Is there a way to add this functionality in this

Do you have a screenshot or sketch of what you want, and the corresponding model?
