Reversible Loading in RAM Concept?

I'm analyzing a PT podium slab using RAM Concept. To do so, I'm generating load combinations that include point loads due to wood shear wall tension and compression chord forces. These forces are equal in magnitude but opposite in direction (tension = negative in concept; compression = positive in concept). I've created a new entry for each positive, orthogonal wind direction in Criteria>Loadings (i.e. I've created a "Loadings" case for wind in the positive plan x direction and a case for the positive plan z direction).

My question is: For a given wind load combination (e.g. 0.9D + 1.0W), can I manipulate the load combination so that "reversible" loading is used in order to reduce the number of unique load combinations required? In other words, instead of creating (4) unique load combinations to account for wind in the +Z, +X, -Z, -X directions, can I create a combination for the Z axis and one for the X axis and tell the program that the applied point loads are reversible (i.e. should be multiplied by a factor of -1)?

Thanks!
