Hi SD Team,

I'm familiar with the Import PDF feature and I'm looking for a workaround to have an imported PDF being monochromatic (showing only one color). 
One reason is that the imported PDF should be visible as a background and should not be confused with the added SD symbols.

My issue is that if I select all objects of an imported PDF, changing Fill Color, Line Color and Font Color won't give the expected result. eg a rectangle without a Fill color becomes filled.
And it's practically impossible to select all objects one by one to change the relevant color attribute because of the large number.

I'm looking for the similar feature of the "Black & White" option when importing a DWG file but with the choice of a color in addition.

Is there a way to achieve this in the current version ?  otherwise can you put this feature in a future version ?

Thank you,
