Set host for elements

I’ve created a dynamo graph some time ago to make it easier to draw certain elements. Now the drawing has finished, we got the demand that every element in Revit has its host (the level, which apparently it doesn’t have even though the elements are on levels). To be perfectly honest I’m not familiar with hosts in general.

I’d be really happy with some simple start up for this just so I have an angle to start working from.
