Yes, but as I wrote, such patterns are useful, good ones and I'm looking
for an alternative form for them.

Also note that ##/* in your example is applied before file generation.

Yes, I simplified the case again, the complete example is:

list=3D( ${(M)~ZINIT_ICE[pick]##/*}(DN)
$local_dir/$dirname/${~ZINIT_ICE[pick]##/*}(DN.) )

It matches either the absolute path given in pick, or applies it inside the
local directory.
