Numbering multi episode files with random episodes

Sonarr version (exact version): 3.0.4.1011
OS: Windows 10
Description of issue:

Is it possible to type episode numbers in multi episode files in such a way that Sonarr will not think it contains all the episodes in between as well? For instance, one file contains episodes S01E01, S01E03 and S01E05, but not S01E02 and S01E04. Typing S01E01E03E05 and any other pattern I could come up with is interpreted as E01 - E05.

No it’s not, Sonarr treats multi episode releases as contiguous numbers, which is required to support range based naming E01-E03, releases with gaps in the number like you’re describing is a case that Sonarr does not support.
