Yes, at no extra cost :-)

objects used in this example:

fld "list", which will have line selected
(NO multiple hilites, please ;-)

fld "to add", which holds the string to add :-)
can also be a variable, of course...

btn "insert", with one of these scripts:

1. to add a line before the selected line:

on mouseup
put the hilitedlines of fld "list" into hl
if hl = empty then exit mouseup
put fld "to add" & CR before line hl of fld "list"
end mouseUp

2. to add a line after the selected line:

on mouseup
put the hilitedlines of fld "list" into hl
if hl = empty then exit mouseup
put CR & fld "to add" after line hl of fld "list"
end mouseUp

Tested and works ;-)

You might want to use the alt-key to combine
these scripts a la:

if the altkey is down then
## before...
else
## after...
end if

after 'rasslin' (Sie Mittel-europear haben die Kaubois gern, nit?)
with the user interface for line insertion conundrum, the most
intuitive approach seems to be mimicking a word processor.
 
that means trapping for mouseClicks before, on, or after the
(linked) text on a given line.
of course you need some spaces before and after
the text on each line. 
you need to allow for a single mouseClick or a second 
mouseClick bracketing a line.
 
then you can easily use the data to 
copy, paste, or cut a line. all on an "Edit..."  list button.
it gets really challenging if the contents of the lineS of text have to be adjusted relationally.
 
the satisfaction inbuilding a real editor,
however primitive,  is enormous.
