Possible to "Show all files (recursive)" in only 1st level?

[grafical]

I want to add IPTC tags to files in a directory structure under a common root folder.
When using the "Show all files (recursive)" function, is it possible to restrict the resulting list to only the first-level of subfolders? For example:

root\
\level_1\
\level_1\
\level_1\level_2
\level_1\level_2\level_3

In the tree above, only files in "level_1" folders should be processed, and anything below any of them would be ignored...
Also, only files of a specific type (i.e. TIF) should be processed, while other formats are ignored.
For example, only TIF files in level_1 folders, while ignoring all other files-types in level_1 and ignoring all files in all deeper folders.
