I need to create two versions of a document, one in future tense and one in past tense:
Document A: The consultant will do X.
Document B: The consultant did X.
In the past, I've handled this by writing document A, then editing a copy into document B. This creates problems when making major changes; I can try to modify both documents simultaneously, or I can just edit document A and recreate B.
Neither of those approaches seem very efficient. Are there any well-established processes or patterns to handle this challenge? Is there a term to describe this scenario? Just knowing the right terminology would help me in researching this.
