How to show requirement details in System Requirements box?

I'm linking Simulink with Requirement management in JIRA using Validation and Verification Toolbox.. So far everything goes good using URL Mechanizm. The problem is that beyond the link to Jira Issue MATLAB holds no other data from the Requirement. E.g no name or description. To do this I think I need to implement custom requirement type, where I should add detail function, which should parse the link and return contents af the appropriate fields to MATLAB. But the first question to find - is there any possiblity to view Details of requirements somewhere in the model, other then to generate the report? "description" field in Requirements dialog box is not suitable for this, as information there is not updated when I change source requirement in Jira.
