Dmytro, how well defined are the contexts where these occur? If the patterns 
are well enough defined, you could probably automate all the replacements with 
\partial by using a regular expression across all the files that is centered on 
looking for the s2 sorts of things. Whether it would work would really depend 
on how predictable these things would be. It would be much simpler if you were 
using bar checks as then there would be something in the pattern to anchor the 
search on, but your example

d2 s2 \bar ":|:"

could be accounted for with something like

Search string:
([a-g](?:is|es)?2) s2 \\bar ":\|:"

Replacement string:
\\partial 2\r\1 \\bar ":|:"

Depending on your environment, you might have to modify the strings to match 
your flavor of regex. I've tested this pattern and it accounts for your test 
case. Where it would break down is if these partial measures are variable in 
length or if you have variable numbers of notes before the spacer, in which 
case it might not work. If there is anything that indicates the measure bar 
line location that starts the partial measure, it should be possible (even if 
that something is just a new line).

If you aren't comfortable with regex and would like me to look at some examples 
to see if you could automate the replacements, let me know off list and I may 
be able to help if you want to see if it's possible to fix these that way.
