Apply modifiers to only some vertices?

Ok, so I have a model of a girl in a jacket. I want to apply the shrink wrap modifier to only some of the jacket. Is this possible without splitting then rejoining the separate areas? Thank you everyone

Create a vertex group of the affected vertices and put the vertex group name in the Vertex Group entry of the shrinkwrap modifier

Vertex Groups entry in the blender manual

Thank you! That helps a lot
