I have a feeling that those who could smoothly implement such a thing are no longer with the company. If Glassdoor is to be believed, the Cobra engine is not a very easy or intuitive engine to work with, so a lot of figuring out how to implement stuff probably boils down to figuring out what the last guy did. After figuring that out, you have to figure out how to make what he did do what you want to do without breaking everything.
This is a big problem with super long-term projects like this. If you have high turnover, it makes even simple features monumentally more difficult to implement if the dude who built the framework is gone and left bad notes.
