Apps Any app to modify calendar entries?

[NME42]

Did a brief scan, but did not find any apps for the AW (and don’t want to buy an app to see it can’t) that can modify calendar entries on the watch.
As one can add entries it could be possible that modifying is also possible.

Thankful for a hint.

I’m also very interested in this. I’ve been looking for one for a long time.
