Hi everyone!
I'm trying to add some metrics to my workflow, and I would like to measure how often did a card return from testing. My plan was to add a text field, and update it each time a "test didn't pass" transition happens, appending value (a simple symbol '*') instead of replacing it. As a result, I was expecting N symbols '*' after N transitions, which would be pretty informative.
Sadly, the "append" checkbox doesn't have any effect: whether it is on or off, after several transitions the field contains only one asterisk.
Is that a bug? Is there a workaround for it?
