multingual shortcut alternate

Untitled.jpg
i had multiple alternate for ‘A’. including the multilingual.

if i had six multilingual for each ‘A’. so the count of multilingual as 12.

do i need create 12 alternate on each? so it will be as ‘ss.012’ in opentype features engineering

is there any shorcut?

I think it depends on the actual usage of the alternates. Are these localized versions, or specifically aimed at stylistic sets, like double-storey a, etc.
