 An example of when you may have to deal with that is when you have many input files in a task, and some of these files may have the same filename. In this case, a solution would be to use the `stageAs` option.
 :::
 
+### Dynamic input multiple file names
+
+In some cases, it might be necessary to stage in multiple files, but keep a folder hierarchy or change the
+naming for each file individually.
+Therefore, you can access the sourceObj and storePath of each input file.:
+
+```groovy
+fasta = Channel.fromPath( "/root/*/*.fa" ).buffer(size:10, remainder: true)
+process blastThemAll {
+
+    input:
+    file {"${sourceObj.parent}/${sourceObj.name}.fa"} from fasta
+
+    """
+    find . -name "*"
+    """
+
+}
+```
+
 ### Input type `env`
 
 The `env` qualifier allows you to define an environment variable in the process execution context based on the input value. For example:
