You don' t have to reopen, you can Ctrl-Z or at worst use File>Revert if you don't export to the source image. You can also reopen the last-run filter dialog with Ctrl-Shift-F, so you would have to only change one parameter.
I don't know of any one-to-many filter runners, all those I heard of apply the same set of parameter to multiple images.
I can post later some code that you can run in the python console if needed. What combination of ranges do you want to try?
