You are welcome, true, for other tools that are not mentioned in the Integration Compatibility link, you may have to look at using other alternatives.
You could always post the question with regards to the other tool you are looking to integrate with CA Spectrum here in CA Spectrum Community, if someone has done it, they could guide you.
Secondly, you could also create an Idea here at CA Spectrum Community to provide Out of box integration support to the other tool, this is for the Project Management (PM) to have a look at. When you create an idea, and if it gets many up-votes, PM could look into it and who knows this may get incorporated in the newer releases of CA Spectrum . Therefore it is always worth to post an Idea.
