Add Translation into Series

[Aryan]

Chandrakanta (Chandrakanta Santati #1) have been translated into Malayalam into 2 ways:

In Two Volumes:
Part 1 of #1: ചന്ദ്രകാന്ത part1
Part 2 of #2: ചന്ദ്രകാന്ത part2

In a Single Volume: ചന്ദ്രകാന്ത Chandrakantha

The Single Volume can be added as an edition of Chandrakanta (Chandrakanta Santati #1). But regarding the two volume translation, I am not sure how the numbering would work or even if they should be added in the same series.
