Feature Request Title: All incidents filter
Description of Feature Request: The customer wanted to filter the Incident view based on sub-category. I could see that the filter view in Incident has no sub-category as well by trying to replicate this. Same with the customer's screenshot: https://snipboard.io/QJgABF.jpg
Does a similar feature already exist? no
