In Cura, I can edit my .ini profile settings as needed, for example, when I change filament or models. It's annoying to have to edit the profile on another computer and update it on my Pi just to change the infill, etc. I've searched http://plugins.octoprint.org/ and can't find any plugins that do this.
There is an import function. https://github.com/foosel/OctoPrint/wiki/Plugin:-Cura
Btw. now in Cura 2.1 you'll also need to reimport your .ini.
You can manually edit the .profile by using an SSH terminal program (e.g putty) to log into your Pi
Then cd ./octoprint/slicingProfiles
ls to see folders (on mine I see cura) cd cura ls to see profile files e.g fred.profile sudo nano fred.profile
move down to where you can see the slicing parameters and edit away
