I don’t believe so (with the warning I don’t generally use parts editor and so may be wrong.) The parts editor was not complete when development stopped in 2016 and so far the developers have not issued an update (although I believe there is a project ongoing.) I find it easier to edit the underlying files directly rather than fight parts editor. Instructions to do so can be found in this tutorial although it is not particularly easy. You are best off to run parts you create through FritzingCheckPart.py (listed in the tutorial) as it will correct a variety of things that the svg editors do that Fritzing doesn’t like. You can also post questions here and one of us will generally answer (uploading the malfunctioning part’s fzpz file is the best bet to get help!)
