Add notes to test emails?

Hi there,

We send a large volume of emails and are frequently proofing 4-5 emails at any given time. In Mailchimp it’s super easy to add a quick note to each test email that goes out to disambiguate the different emails either by date, audience, or other attributes. This doesn’t seem possible in Klaviyo? I’m wondering if I’m missing anything? Going back & forth to enter test email notes in the subject line of the production email and then trusting that those notes will be removed before it ships is a bit tedious and nerve wracking, to be honest.

Please let me know if we’re missing something, or if not, please consider this a request for this feature.

Thanks!
