Spot levels in Layout - Changine/hiding units

Is there a way to do either or both of the following. With the Autotag Spot level feature in Layout - it works fine to pick up the levels in the model on the site plan and I am able to change the prefix to ‘RL’ (Reduced level) for our local conventions. What I can’t find a way to do however is to change the units to metres or failing that, turn off the ‘mm’ display of units for the Z ht. Apart from that, I think the tool works fine.

What I did was to create a dynamic level marker component in SketchUp that takes its z position, adds a base level (if the model’s zero level doesn’t match sea level) and converts the result to meters. I then reference this parameter in a LayOut label.

@Anssi could you share this component?

Thanks for your input. Seems a decent workaround and initially I was doing something similar with a component at the z axis in skp. Then I found the autotext enabled spot level and was pretty impressed with the initial ease. Still hoping that there’s a ‘button’ hidden somewhere to be able to toggle off or change the ‘units’. I initially thought it might have been via the dims dialogue - but no dice.
If they don’t yet have that function - it would be great if it’s added to the list of things to make SketchUp/Layout better.
