Matching Drag and Drop


I'm trying to set up a simple Matching Drag and Drop question.  I have four matching options. I have set the attempts to 4.  What I'm wondering is if they quiz taker matches only 2 out of the 4 correctly on the first attempt, is it possible to set it so that the two correct answers aren't changeable and they only have the two un-correct options to move.

Thanks for your help.
