using shapes with ScribusGenerator

[zeroheure]

Hi
I wanted to use Scribus pre-defined shapes with ScribusGenerator, so I browsed the XML in the SLA file. Looks like it is not possible, the shapes are defined with coordinates and the FRTYPE number is the only way to recognize them. Am I wrong ?
Is there a way to use other shapes, like ones created with Inkscape, with ScribusGenerator ? Did someone already tried this ?
Any help welcome. Thankyou.
