Changing default settings of Rhythmic Slash Notation

Hello everyone,

Forgive me if this topic has already been discussed somewhere else. I would like to change the default settings of the "Toggle rhythmic slash notation" feature. Currently, when I select a section of music and toggle to rhythmic slash notation, the default settings force all notes to the middle line of the staff, with slash note heads and stems facing down. The inspector shows the notes fixed to line 4. Is there a way to change the settings so that the notes are instead fixed to line 0 with stems pointing up? It will save me a ton of time if I can figure out how to do this.

Thank you all in advance!
