Diamonds can take as many soil layer profiles into account as you have.
But the bigger question is “Is it meaningful to take multiple soil layer profiles into account?”
Traditionally, a soil investigation company performs 3 cone penetrations tests (CPT) on a property. Because it creates a safety net: if 1/3 tests fail for sone reason or if you suspect that the measurement was incorrect, you still have the other 2 tests to fall back on. Of those 2 tests, you take the mean values and merge it into one soil layer profile which you define in Diamonds.
So having multiple soil layer profiles for a small property (like a house) is not meaningful. Having multiple soil layers profiles for an extended property (like a parking garage spanning 100m) makes more sence.
