Import Sub-entities for Activities (Notes, Dependencies)

Is it possible to import notes for activities?

I am loading activities from an existing MS Project into Projeqtor, and for the most part it is going fine.  I cannot see a way to import dependencies or notes however, and manually creating them is very time consuming (500+ tasks).

I see that there isn't a standard 'import' for this in the Import Data module, but wondered if it is possible any other way - maybe a python script and an API?
