You are actually doing the correct by using a custom process strategy.

Sorry we cannot support every single end user requirement by adding
new special headers/properties etc.
The file/ftp components is already a lot of functionality out of the
box. And adding this kinda leads to confusion.
What we may do is to let the move expression leave the file as is, if
the result is null/empty. Then we could skip moving the file.
Then you can just implement a bean and use that to compute the file
name if the file should be moved, or return null/empty if to stay as
is.
"file:inbox?move=${bean:myMoveBean}"
<bean id="myMoveBean" class=..."/>
And then you can just have a bean with a method that has the logic.
And you can use the Camel bean parameter bindings etc.
public class MyMoveBeanImpl {
public static String moveName(@Header("CamelFileName") name) {
...
}
}
