I have a huge text which mostly consists of numbers and very little actual text, and even if it is 98% match it is super difficult to change each number (and you can make mistakes easily), much easier to copy all source text to target and then go through the text and translate individual words. But I don't seem to be able to propagate only 100%, I have changed minimum match value to 100%, but it still gives me smaller matches too.. 

What I do now (or what I plan to do): So first I copy all source to target, and then I plan to go through the file and translate little bits of words (and use replace option to replace the words - it is a bank statement, so there is almost no text and any text there is - is literally "account number" "date" etc.. 

Can someone give me an idea how to do it better? Because as I said, if I get even 98% match it means I have to go through all the numbers and check every number and the file is huge, but close to no text at all. And it keeps propagating even 70% matches :((
