Search Function Capability for Event Numbers

It would be nice if Marketo's search function could include an option for Event Numbers, like On24 for example. It would allow us to pull up events even without having a program name handy. Currently, when we are provided with an On24 URL there is no way for us to find out whether or not that webinar program already exists in Marketo or not unless someone happens to remember the event and the associated program with it. Maybe instead of having just the search bar there could a drop down where we could choose what we are searching for, like program, event ID, etc.
