If it is a "crushed" in hole, (where the simulated grain is still showing but just pushed in)you can drizzle some minwax satin polyeurethane into the dent till slightly over level but not spilling out. Let it cure for about 3 days and lightly sand the area till level or if it cured and shrank some refill till it is level. Either way, after it is absolutely level with the uneffected area, softly scuff a few times with about 220 grit, and brush on a final coat of polyeurethane covering and surrounding the hole/dent by about 1". The idea is to create a lens which brings the illusion of the crushed area to the surface. At first it will look very shiny but give it a chance to cure and dull up to the satin pergo surface. It works. It blends right in if you did it right. So much so to the point that you have to get down and hunt for it on hands and knees. It also sure beats tearing up so many planks. If you are very concerned about blending the finish right in at the edges of the poly, use some mineral spirits or turpentine on a modelers brush to eat away and spread the poly thinner by progression outward till it disappears into the unaffected area.
If it is a gouge with missing laminate, maybe some pergo putty filler and some fancy pen work with a stain stick/pen/marker to simulate the grain followed by the poly method will work.
