What is the current behavior?

I want to use allure to generate report, and especially write some data into the report dynamically.
We already did implementation for data like: feature, title, description, ... and it is working fine.
But, in the case of sub_suite, if it is NOT defined in the pytest script, with @allure.sub_suite('value1'), then it will add to the report a new subsuite, automatically with the name of the class.
Then, when I add the subsuite with allure.dynamic.sub_suite('value1'), I have in the same report:

• {"name": "subSuite", "value": "className"}
• {"name": "subSuite", "value": "value1"}

If the current behavior is a bug, please provide the steps to reproduce and if possible a minimal demo of the problem

• Do not define any subsuite in the pytest script. eg: @allure.sub_suite('value1')
• While generating the allure report dynamically, use the function: allure.dynamic.sub_suite('value1')

What is the expected behavior?

Only 1 entry should be available in the allure report:
{"name": "subSuite", "value": "value1"}

What is the motivation / use case for changing the behavior?

Get data from a configuration file or document and define the data based on those files, dynamically.
