Influencing XML formatting in scala

Is there some way to influence the plugin with regards to the formatting of XML in scala? The XML I'm generating has 20+ elements which chews up more lines than I would like.

What I get...
val xml = <elements>
<element>
  <id>
     {id}
  </id>
</element>
<elements>

What I would like...

val xml = <elements>
<element>
  <id>{id}</id>
</element>
<elements>
