Using Bulk Editor to target all descendants within directory

Hi!

I'm using Bulk Editor to import TSV files in order to add image paths to content pages in AEM, similar to this example:

Instead of six rows where each subdirectory is specified ("/child1/", "/child2/", "/child3/"), is there a way to accomplish this same thing by targeting the parent directories ("/parent1/", "/parent2/"), thus affecting all descendant directories contained within?

The solution I'm hoping for might look something like this:

...for example, where by targeting /parent1/, files within descendent directories /parent1/child1/, /parent1/child2/, and /parent1/child3/ are all updated with the same image URL.

Hope that's clear. Thanks in advance for any help!
