Qualys VMDR integration, add Qualys Tags in documents

Hello everybody,
we are an MSP providing security services for our customers.

The customers in our Qualys environment are divided by different tags inside of Qualys, like cust:CUST1, cust:CUST2...

For now we use a self-written script to get that data from Qualys into Elasticsearch. The script checks for the qualys tag and uses that to send it to the correct customer ELK-cluster.

We've now tried to mimic this behavior with the Qualys VMDR integration. The integration itself is working fine and getting all data from the Qualys API.

However, there is no field showing the attached qualys tags in the asset data documents.

Is there any way to make the integration grab those as well?
