Is there a way to configure/manage IR subscriptions directly in APEX?

Can Interactive Report subscriptions be managed/setup by accessesing the system APEX tables directly? If so, which are the key tables that need to be looked at?

I want to be able to see and change the subscription settings (ie email addresses, start/end dates times) and report parameters that were in place when the IR subscription was set up by looking directly at the database (and not have to revisit each IR in their app pages individually via the app builder).

Any guidance much appreciated!
