Can I paint in transparency mode?

[tryphon4]

I aim to directly paint using transparency modes, e.g. using multiply or luminosity transparency, as it is possible in several other products like Expression.

I know that there is a trick: painting a line, adding transparency, then copy-pasting format/attributes to other objects. It works but it is not elegant.

Do you know a way to paint using transparency modes in Xara (using Art or Scatter brushes, e.g. creating a luminosity brush, a multiply brush, etc.)?
Thanks.
