How can I preview a template for a specific event?

Is there any way to preview an email template for a specified event, not just one of the most recent 10 events?
Sometimes when we're building email templates, we're looking to cover specific use cases that don't happen very frequently. Only being able to preview one of the last 10 events is limiting, because the example events that I'm looking for often happened well in the past, or the rate at which we're receiving events means that they age out quickly.
Within the email template editor/preview, I'd love to be able to specify an event ID as the preview data source, as well as have the associated event and profile properties display in the sidebar.
I have been accomplishing this on my own computer by using Proxyman scripting. For the call to https://www.klaviyo.com/template/*/preview, I rewrite the event_id parameter of the request body to the activity ID (Activity Id: 7xRY7x2dxzX) from an event that I've identified.
However this is only a local solution, and I’d like a way for others to be able to accomplish this using the Klaviyo UI.

Thanks,
Joanna

Hi ​@joanna at thuma 

I agree: the preview of just the most recent 10 profiles that triggered an event is a frustrating limitation (templates & flows) and is something I hope Klaviyo will address. I’d like to be able to grab any profile from an event’s activity feed in metrics and preview that event as that profile.

A workaround is to trigger the event using a test account which will bump that profile to into the event’s 10 for preview. Not ideal as that’s additional effort, and the clock starts ticking; if you have a lot of events firing, and if the time to test is lengthy, your test profile will quickly get pushed out of the 10. 

I appreciate this approach won’t work well for your team review, but it may help others on this forum.

Sorry that I don’t have a better solution! @GabbyEsposito anything to add from Klaviyo’s side?

Regards

Andy
