Allow custom selection of email performance metric shown on workflow email actions

Idea:

Currently, when you add a “Send email” action in a workflow, the canvas displays a fixed performance metric (click rate) directly under that action step. It would be great to have the option to choose which metric is displayed here instead, for example, open rate, click rate, click-through rate (CTR), or bounce rate.

Why this matters:

Different teams prioritise different metrics depending on what they’re sending. In an example of something built today, I sent transactional emails through a workflow that don’t contain any links to click, so click rate isn’t a useful metric for us at all. All we actually cared about was open rate, but there was no way to see that at a glance on the workflow canvas. We had to leave the workflow and dig into the separate Workflow Details or Email metrics just to check something as simple as open rate for that email step.

Suggested solution:

Add a small dropdown or settings icon on the email action step, similar to how other workflow action displays can be customised, that lets users choose which single metric is shown under that step, with open rate, click rate, and CTR as initial options.

Additional context:

This would be especially useful for teams sending transactional or notification-style emails with no clickable content, as well as anyone managing multiple workflows with several email steps, where seeing the right metric for each specific step at a glance would save time and make performance issues easier to spot quickly.
