Pedal Steel Guitar tab

I'd love to see a way in tab preferences to write for the use of a bar/slide. This would mean that all the frets needed to be the same all the way across. Is there such a feature and I'm just missing it? Thanks!

For context, I'm tabbing for 10 string pedal steel, using a linked tab and staff. Writing chords in the staff and letting them automate in the tab. Because the pedals change values of the strings to give new notes, there will be some deviation from the bar, but it's usually a half/whole step raise/lower. I'd love to have a way to keep groupings on as close to the same fret as possible, rather than automatically moving to the lowest possible fret.
