cross-reference to [annotate\_amplitude for a specific time window - #13 by FranziMNE](https://mne.discourse.group/t/annotate-amplitude-for-a-specific-time-window/5329/13) where the question of rejecting on PTP amplitude vs. absolute amplitude was already discussed. Suggestion there was to allow `reject` to take a callable function; happy to review a PR if anyone gets excited about implementing it.
