Hi blackboard, sorry no there isn't any way to make an object just partially translucent instead of 
fully transparent.
 
You can have an overlay image coming from a bitmap image file though. You do that by putting in 
the image using the View > Images command.
 
When you are in that View > Image command you can set the option to have images drawn above 
everything as an overlay and adjust image transparency to a partial level:
