This is fixed in v2.2.13. The implementation inserts a one-second pause whenever it detects a change in the sutta_uid portion of the segment id. For suttas such as AN1.1-10, this will have no impact whatsoever since the segment id's are of the form "an1.1-10:...". However, the pause will appear in multi-sutta playlists (e.g., "mn1, mn2").

Regarding customization, we felt that is best achieved by simply hitting the Pause button on one's audio player. The newly introduced one-second pause provides ample opportunity to "take a meditation break" between suttas. Automating such a feature as a user preference creates storage challenges on the web server given the large size of the downloaded audio files.
