Exisitng MWBC

[infinity]

Two questions regarding posts on this topic.
1. If I install multiple multiwire branch circuits in a conduit in lieu of taping them together at the panel end and what not would it be allowable to tag the neutral conducter with the various circuit numbers? For example 2 4 6 on one and 1 3 5 on the other which clearly identifies it which I believe to be the intent. Correct or not?
2. Can I use two single handle ties to tie three breakers together?
Thanks

No and no. IMO the individually number conductors is better than a piece of tape but the NEC makes no provisions for using them in lieu of the tape or a cable tie. Only MWBC's in a common raceway require the tape or cable tie identification. A single MWBC in a raceway or multiple two wire circuits in a common raceway do not require the bundled identification.
