Is this really the best solution for regexing?

[Deanosim]

I'm trying to download from https://roosterteeth.com/series/rwby but in Sonarr the episode names are like this The Shining Beacon (1) The Shining Beacon (2) and on the site it's The Shining Beacon The Shining Beacon, Pt.2
the best solution I could come up with is

    regex:
      sonarr:
        match: '[A-Z][a-z]* [A-Z][a-z]* [A-Z][a-z]* \(1\)'
        replace: 'The Shining Beacon'
        match: '[A-Z][a-z]* [A-Z][a-z]* [A-Z][a-z]* \(2\)'
        replace: 'The Shining Beacon, Pt.2'
        match: '[A-Z][a-z]* [A-Z][a-z]* [A-Z][a-z]* \(1\)'
        replace: 'The First Step'
        match: '[A-Z][a-z]* [A-Z][a-z]* [A-Z][a-z]* \(2\)'
        replace: 'The First Step, Pt.2'

But it seems like a pain, have to enter the episode name for every episode, tried entering regex in the replace Field and it just printed the regex
