How to set soapui-log4j.xml when using smartbear/ready-api-soapui-testrunner dockerimage?

Hi, I have already tried to find a Solution for this, but I couldn't find anything usefull.

We are using ready-api-soapui-testrunner from dockerhub four our automated Tests in a Pipeline. Now I would like to know how I can provide a soapui-log4j.xml to this ready-api-soapui-testrunner. Is it even possible?

Btw. it would be nice, if there was a dedicated section for those using the dockerhub Image.

Thanks.
