You're absolutely right, we should provide this functionality. In fact, we've even had our own applications engineers request it (great minds think alike!). It's on our roadmap, but we don't yet have a release date for that feature.
We have made a number of user interface updates in the upcoming PSoC Designer 5.3, though. I hope you check them out when we release at the end of next month. I think you'll like what you see.
Thanks for the feedback
