Dead Space 3

Hi I purchased the special edition of dead space 3 and got dead space 1 and 2 for free.  Dead space to got added and installed wirthout issues (I have dead space 1  + 2 on my steam account)  However Dead space 2 was already listed on origin and I never bougth it on there, so had to copy and paste my serial number from Steam to get the game to work.  So could this steam copy be removed from my origin accoutn and a new dead space 2 copy be given which I havepaid for buying dead space 3.  Then I will be able to use the serial no from origin,

Thanks
