Hi Nicolas,

You should be able to create and import named selections of edges from ACP Pre system to the analysis system

Or see if you can use worksheet named selections. In the worksheet you can specify a crietria and select elements or nodes. For example, you can find nodes at specified X, Y and Z coordinates 

Check this help section: Understanding the Named Selections Worksheet (ansys.com)
