Snap skeletal mesh to bottom of capsule?

Say theres a parent BP and 50 children. Each child has a different size skeletal mesh. So when putting them all in a level, some walk around normal, others look like their floating. The meshes are different sizes so im assuming they’re all relative to where the parent mesh is. Is there a way on begin play to find the lower part of the capsule and the lower part of the skeletal mesh and make sure they’re snapped together?

Using the following setting to align the skeletal mesh with the character capsule.
