Adding Lifecycle to RT:IR?

Hi,
I have a situation where I need to track a specific action, and it seems to be a perfect usecase for a separate Lifecycle.
So this is basically a request to release something from a quarantine. I want to have actions that correspond to “Release” and “Deny Release” as actions. So that would be a separate Lifecycle.
But I also want to be able to use the “Link to Incident” and “Create Incident” workflow that is present for queues that are in the incident_report Lifecycle.
Is there a way to add a second lifecycle to the lifecycles RT::IR considers its own?

I see that there is some code that seems to hard-code the names of the lifecycles in …/local/plugins/RT-IR/ib/RT/IR.pm And I guess hacking that file is possible, but I would prefer not to.

I just want RTIR to trat this queue/lifecycle as “belonging to itself”

Does anyone have a suggestion?

Thanks

Would you be able to edit the existing RTIR lifecycle to accomplish this?

Yes, that is what I have done for now. But that makes the other states available in all the incident report queues.
While not a showstopper, it is inconvenient.
