Today, it is not possible to create a jsonpath preprocessing, where I limit the output using a regex filter to remove data ?

I know that I can use a regex filter to select data, but I need to opposite - remove selected data.

From https://www.zabbix.com/documentation/7.4/en/manual/config/items/preprocessing/jsonpath_functionality, I know that I can do

$.books[?(@.title =~ " of ")]

but this does not work:

$.books[?(@.title !=~ " of ")]

It would be great to have this included in i Jsonpath preprocessing.
