The PTR is an entirely separate database because of this the technical hurdles that would have to be overcome to make such a feature is impractical. Here is a dev post that explains more:
Game Director Jeff Kaplan:
I really appreciate your post. I agree with a lot of what you’re saying.
We’d love to improve the PTR experience. The difficult part for us is that the same time and resources we spend improving the PTR experience could go towards improving the core game. For that reason, we usually favor the latter.
We do frequently discuss the topic but we’re wrestling with making the correct choice. To provide one example: The same people who would work on match history or replay features would be required to work on making EXP carry over from the PTR to your main account.
Usually, people respond to comments like this by saying “just hire more people”. My response to that is: Careers at Blizzard Entertainment | Blizzard Entertainment jobs
