Please help with another special regular expression

Problem 2 (which I think is unsolvable):

The formatting I receive from Amazon or freedb looks like this
01 - String Quartet No 14 in d-moll, D 810 - Allegro
02 - String Quartet No 14 in d-moll, D 810 - Andante con moto
03 - String Quartet No 14 in d-moll, D 810 - Scherzo: Allegro molto
04 - String Quartet No 14 in d-moll, D 810 - Presto
and I would like to have it like this
01 - String Quartet No 14 in d-moll, D 810 - I - Allegro
02 - String Quartet No 14 in d-moll, D 810 - II - Andante con moto
03 - String Quartet No 14 in d-moll, D 810 - III - Scherzo: Allegro molto
04 - String Quartet No 14 in d-moll, D 810 - IV - Presto

That would mean that I can do a roman number sequencing action in consecutive tracks I highlight. Until now I have to do all this manually, which is very time consuming

And to make it even more difficult, it would be very cool to be able to solve "elimination of same string elements from second occurrence on", so that it looks like this
01 - String Quartet No 14 in d-moll, D 810 - I - Allegro
02 - II - Andante con moto
03 - III - Scherzo: Allegro molto
04 - IV - Presto

Appreciate your help!
Thanks

Actiongroup:

1. Format Value:
   Field:
   TITLE
   Format String:
   $regexp(%title%,(.?) - (.?) - (.),$1) - $if($eql($left(%title%,2),01),$regexp(%title%,(.?) - (.?) - (.),$2 - $1),$regexp(%title%,(.?) - (.?) - (.),$1)) - $regexp(%title%,(.?) - (.?) - (.),$3)

2. Replace with regular expression:
   Field:
   TITLE
   Regular Expression:

• (\d\d) -
  Replace matches with:
• $replace($1,01,I,02,II,03,III,04,IV,05,V,06,VI,07,VII,08,VIII,09,IX,10,X) -

works for roman numbers I-X, but you can append as many numbers as you need in the last string.

EDIT:
Problem 1 sounds simple:
Include for every every key-signature which sould be changed something like this:

Action: Replace
Field: TITLE
Original: in B
Replace with: in H-Dur

will be a lot of work for 4 different languages and the different key signatures.
