Custom Error Message Alerts

I did find one way, though it isn’t preferred, and that is to use an if/else in the action sequence with a open modal which has the error message in a textbox, though I’m sure I could use some logic like you’re talking about to set flags in a table holding error messages. I was more just hoping there would be an easier way to go about this since the “success alert” exists, I feel like a failure alert would be useful as well just having it built in.
