Placing Floor Span Direction Symbol


I’m working on a script that can automatically place tags and symbols in my views.
The tag-part is working now, but i’m having trouble with my Span Directions.

If i place the Span Direction Symbol with “FamilyInstance.ByPointInView” i get the problem that they don’t have the floor as host Id, and also this parameter is ReadOnly, so it can’t be changed.

The other Tags i place with “Tag.ByElementAndOffset”, this node works perfectly but works only on tags, not on symbols.

Is there a way to place the Span Direction Symbols WITH host id?
