as far as I know there is no filter option in admin...
if you use a custom prop/eVar for the URL you can create a classification with a regex rule to "rewrite" the URL. this leaves the original values unchanged (might be needed somewhere else?) while you have a new dimension for the URLs without the params.
Update the code to record the URL without the desired query parameters. If you are overwriting the default "page URL" variable, I recommend to save the deleted query parameters in a custom prop/evar
