Categorize several Allure reports into a single dashboard

In our enviroment, we generate several tests reports that we want to send to Allure, but we only want to mantain one instance of Allure.

The test reports come from different sources: one coded in PHP, another in javascript, etc. We've already implemented the modifications in the code to be able to send it to the Allure instance, but once we send several test results (we use a python script to put the tests near Allure, so we can do an Allure serve over the folder) it becomes very difficult to differentitate their origin (if they come from the php instance, from karma, protractor...), as they all appear in test suites without any kind of categorizing.

We would like to know if there's any way to categorize all tests results by origin and only use one instance of Allure, so in test suites it displays as such:

PHP Tests Results

1. Test Result 1
2. Test Result 2
3. Test Result 3

Karma Tests Results

1. Test Result 1
2. Test Result 2
3. Test Result 3

Protractor Tests Results

1. Test Result 1
2. Test Result 2
3. Test Result 3
