Ruler for Markup

I have been successfully using the Markup tool on Sketchup for IPad for some time now. I use it both during Zoom meetings with clients–marking up plans and elevations, for example, with options we are discussing–as well for myself to sketch out new design ideas before I return to my Sketchup model.

I could completely abandon Morpholio Trace, which I used for these tasks before Sketchup for IPad, if there was a way to measure within Markup mode. There is a ruler, of course, that comes with the Apple markup bar, but it seems to be only useful to draw straight lines. Is there any possibility that the Sketchup tape measure tool could become usable within the Markup tool? This would allow for much more precise sketching, which at some point I often need to do.
