Mensurstriche spacing question

Hi folks!

I wonder if anyone has any advice on achieving good note spacing when using mensurstriche with the 1:1 tuplet trick to avoid written ties. The issue I keep running into is that if there are no new notes on the downbeat of a measure, Dorico narrows the measure such that it looks like the first note(s) in that bar occur on the downbeat, regardless of their actual rhythmic position. The workaround I’ve been using is to add hidden quarter notes in a second voice to force Dorico to allow space for those beats, but I don’t love it and I wonder if there’s a more elegant solution. Any other suggestions?

Here’s an image of what Dorico does by default, and then the desired spacing results with my hidden note trick:
