Hi AJ. In order to support such expectations for enthusiasts such as yourself, we have an API mechanism that be used to fast track the creation of custom attributes. Take a look at the simple documentation on CA WIKI: APM REST API - CA Application Performance Management - 10.2 - CA Technologies Documentation
Also, we have direct integration with Jenkins officially available on Jenkins page. Look for CA APM on that page and follow the steps to install that piece. The Jenkins integration provides auto-creation of attributes for the latest releases. Also, it has great code quality control feature and version compare.
I am also sending to your email a simple script - add-cam-attributes.sh to provide an example use-case of the REST API.
Cheers,
Nik Jain
