When I refresh my data, my Sankey chart goes back to the default formatting and ruins my visual.

[LindServ]

I have spent a lot of time manually clicking and dragging nodes around the page to create a pretty looking chart for maxiumum clarity and interpretation and it takes a bit of time to do. When i bring in new data of any kind and refresh, the nodes go back to the standard evenly spaced rows and a lot of overlap. 

Is there a way for me to retain my formatting? To fix my nodes in place?

Thanks
