Could i use a property (from another datasource) for dynamically named a datasource file ?

Hello.

I have a first file that contain a list of files of data.

I have to run a testcase on each data file.

So i want to :
1. set a first datasource for getting the list file

2. set a second datasource as file with name is a property come from the list (the first datasource)

How should i name the second file for doing this ?

Thank you for your help.
