What is recommended to break this long line?

What is recommended to break this long line? Currently I have:

export NNN_PLUG=\
'a:-!nnn-mpv-audio*;'\
'd:-!|du-all "$nnn";'\
'e:-!&losslesscut "$nnn";'\
'i:-!|mediainfo "$nnn";'\
'I:-!i -ns "$nnn"*;'\
'm:-!nnn-mpv-all*;'\
'M:-!nnn-mpv-all --cache*;'\
'p:!&nnn-mpv-playlist;'\
'P:!&nnn-mpv-playlist --keep-open=always;'\
'q:-!&qimgv "$nnn";'\
't:!trash-archive -nf*;'\
'v:!nnn-mv-to-dir;'\
'V:!rsyncmv --nnn --srt*;'\
'x:!xc;'\
'y:-!nnn-path-to-clipboard*;'\
'Y:-!nnn-path-to-clipboard --basename*'

but shfmt insists on formatting it into a long line making it hard to work with the array-like string. I see disabling formatting is not supported, so surely there is a way to at least prevent it being formatted to a long line. I guess one can break it up to a numerous concatenations str+=${str}abc but that doesn't seem ideal where formatting for readability in this manner technically requires changing how the code is parsed...
