calc graph icons with white background

Dear all,

I am making a line graph with calc, when i select ‘format data series…’ > ‘Line’ tab > ‘Icon’ drop down menu, there is a list of symbols that have the same filling colour of the main line.

Is it possible to fill the icon with white colour, so that ● and :black_small_square: are actually different from ○ and :white_small_square:?

Thank you
