[Feature Request] Easier seed importing

[copy2018]

Current issue:
When you try to import a seed but get one word wrong and the final word is not available you cannot go back to edit the wrong word you inputted, you must enter all the words from the start.

Fix:
Enable us to edit previously inputted seed words if we notice the 24th word is wrong.

You can actually go back by hitting the back button on the top-left until you reach the incorrect word, fix it and continue again from there. You would then only need to re-do the words that follow, and not re-enter the words before it. If you accidentally missed a word or repeated one, you'd have to do that anyway.

Not sure how the UX of fixing a simple typo should look like, and if it's worth the added complexity for an edge case that seems rare.
