[scribus] How to set baseline grid in Python script?

[Eamonn O'Brien-Strain]

In a Python script I can use pass the linespacingmode=2 parameter to the 
createParagraphStyle function, telling to to create a paragraph style in 
which the text should be aligned to the baseline grid.

However I cannot find where in the Python API I can set this baseline grid.

Is it in fact possible to set the baseline grid with a Python call?

Thanks,
