Google alerts: how to sort multiple "alerts"?

Question

Google

Colleagues, help me find a solution. I actively use GOOGLE ALERTS in my work, there are a lot of "alerts", I want to systematize them, but the service interface does not allow this.
Perhaps there are software tools that will track my alerts and allow them to be grouped?

Answer 2

Colleagues, the task has become more complicated - they
are interested in updating the following queries -
site: www.site.ru filetype:pdf OR filetype:xls OR filetype:doc
, that is, the appearance of new documents in the search engine index , an
alert is created, but does not work, for verification, I created a
site request: .gov document filetype:xls
nothing appears for a day
summary - how do I subscribe to the appearance of .xls .dos .pdf documents in the search engine index?
