If you want to e.g. automatically stack new versions of same image to a stack you can configure regular expression to be used to look whether the new file is a new version of an original file. Following settings where first is the search regexp and second original file test should get you started, but might need some tuning to suit your naming convention:
Note that the Original file replacement text can have multiple suffixes separated by semicolon and reference to regexp match can be used in the format of \1. Original file is being searched from the same directory as the new file. Oh, and the example regexp will match e.g. the following files: example_v1.jpg, example_12.tif, example.PNG.
