Non shippable Flow is not creating event when in a SO with shippable items

Summary:

Hi,

I have an scenario where a SO contains 1 line for shippable item and another line with non shippable item.

In that case I would like the proper SFO Flow is picked at line level meaning it creates 2 events calling different SFO flows. Is that possible?

In my case only event for shippable item is created and in the invoice the non shippable line is not present.

Perhaps asking silly question and only one flow can be called for every SO. In that case you won't be able to use within same sales order both shippable and non shippable items, right?
