Abiltiy to add custom fields to Component - directly to table or via relationship to custom field table)

Business Case: We support 65+ small web applications, and in order to know which issue is for what application, we are using components.  The thought of creating 65+ JIRA projects (and growing) didn't work, and labels did not work either so we decided to use components. This has proven to be very effective. However, now we would like to know more information about the component, but we are limited to the out-of-the-box fields.

Ask: We would like to have the ability to add custom fields to the component. Examples would be URL links, General Text fields, Dates, Email, just to name a few.  When looking at the schema, there is no relationship between the Component Table and the Custom Field Table. Could that be added? OR could you add more fields, such as what was state earlier directly to the table.

Thank you very much,
