Hi there,
We have a situation where we need to view the relationships between two connected entities in a concise and information dense manner. An ideal solution would be a grid that would show all the active elements of one entity on the rows and all the active elements of the other entity in the columns. Color coding might be used to show important information, such as the strength of the relationship between the two entities.
Unfortunately, Dynamics CRM does not support matrix style grids for viewing and reporting on entity relationships out of the box.
In specific, we have been tracking proposed features and functionality for our products in our CRM database with a new entity type called, "Ideas". This entity is related to Sales Opportunities by way of a third, joining entity called "Idea Opportunity Links". This allows many opportunities to be related to one Idea and conversely, many Ideas to be related to one Opportunity.
Our issue comes in when we want to view the intersections of these items in an information dense matrix grid view. There are no functions in CRM to allow for this to be done out of the box. Ideally, this grid view could be applicable to other relationships, such as Opportunities to Sales Team Members, etc.
Here is a diagram of what we'd like things to look like: 
If you have any suggestions as to an affordable add-on that could accomplish this task, I would greatly appreciate it. If not, any pointers on how to use the APIs to accomplish this would also be appreciated.
Thank you very much for your help and guidance!
Best Regards,
Eric
