Change Ruin III to Ruin I when synced to a level where Ruin III is not available

[Callinon]

And just in case it isn't clear. I don't mean to remove Ruin I like how Bio II replaces Bio I, I mean to change Ruin III to Ruin I when we sync to a level where Ruin III is not available.

How would that be different from the way Bio II replaces Bio I? So you still want Ruin I to be available when Ruin III is available... but you want Ruin III to change into Ruin I when it's not? If you have to have 2 buttons anyway, what's the point?
