[Plugin: Recent Posts Slider] Overload options

Hello
my RPS version is 0.6.3 and i’ve have to include different RPS in different pages WITH different options. I use the_widget(‘RpsWidget’, array(..)) function each time.
Could you tell me how to overload options defined in administration. Aren’t they only default values for options ?
Thanks for your help.
S.
