Yes, that's how I normally handle this kind of situation. EG, I might
write:
openF =. (&,:) (@:>) ($&1...@$&>`) }
or, if I were in an editorial mood:
openF =. ("_) (`,:) (`>) (`:6) (($ $ 1:)&>`) }
in either case,
_. openF (i.3);(i.5);(i.7)
0 1 2 _. _. _. _.
0 1 2 3 4 _. _.
0 1 2 3 4 5 6
The concept is the same as you outlined: you figure out where the fills will
be, then use that as an amend mask between your input and an array of
(custom fills). And it's not as complex as you might expect: you know how
to figure out where the fills will be? You use open, of course :)
