Default Data Modeling layout to Collie-style

I use the Collie layout methodology (Dim on top, Fact on bottom, filter directions downhill) in all my data modeling. When Power BI builds automatic table relationships, the layout it ends up with is almost always a mess and I have to spend several minutes moving tables around to get into a Collie layout. Would be great to have an option to have Power BI attempt a Collie layout by putting Dim tables in a row along the top and Fact tables below, minimizing the number of connector lines that cross.
