I'd rather keep the titles on the document the same as in this timeline for convenience, but I was also thinking of renaming the different timelines for their respective years. Like "Alternate 2012/2013/2014 Timeline" for Endgame, and "Alternate 1930/2091 Timeline" for AoS.Since there are more and more alternate timelines appearing in the MCU, the "MCU Timeline Reasoning" Document seems a bit too messy with all the items just having the alternate timeline name next to it. I suggest that maybe the document should have a new column which states which alternate universe the item is actually in, while the main MCU timeline should just have a blank or all have "MCU" filled in.
For timelines that doesn't have an official name yet, we can just write the initial appearance the alternate timeline is in (a show or a movie), and if multiple timelines are introduced, then we can write a number according to the sequence of appearance.
For example:
"Avengers Endgame 1" (2012)
"Avengers Endgame 2" (2013)
"Avengers Endgame 3" (2014)
"Avengers Endgame 4" (1970)
"Avengers Endgame 5" (1948)
The placeholder name can be changed once an agreed name is established (Like "Loki" replacing "Avengers Endgame 1").
I don't wanna sound demanding, so I'll just say this is just suggestion, whether to implement this is for you guys to choose.
I think the Loki series will involve 2012 Loki from Endgame, so I'll apply "Alternate 2012 Timeline" to that one as well.
How about putting the cells in different colors in the document as a compromise?
