now I try to automatize the creation of variable distance buffers for a line vector-layer with the help of the Graphic Modeler in QGIS. I don't want to save the buffer results as a new shapefile but instead adding the new features automatically to an existing shapefile (just adding not overwriting).
The problem thereby is that I can't specify the output in this way with the Graphical Modeler. Is there any possibilty to achieve this?
