want to either eliminate need for selecting a param or occupy the space

Hi we run 2016 ssrs enterprise and develop using vs2010.  I have a param that I would either like to be forced (for now) to a value of N/A or just have a placeholder occupy its current space.  Even though I allow only one value ssrs still makes me select it.  I need it to continue occupying its current location because further down there are pairs of params that need to be across from each other horizontally.  I can already hear the lectures but unfortunately till we get to the next release of the product (cant recall if that's vs or ssrs) I'm stuck with this 2 column param thing in ssrs.
