Option to Type in Answer per Card rather than per Rem

Sometimes we might want the “reversed direction” to be slightly different from the “forward direction” on a two way flashcard.

For example, consider a card like $2^{31}$ <> 2147483648. Here we try to memorize the value of 2 to the power of 31, on the left side is a latex equation, and the right side a plain number.

For the “forward direction” of this card, we have “type in answer” enabled to carefully check that we memorized each digit correctly. So far so good!

For the “reversed direction” of this card, we don’t actually want to type the latex equation in whole; we would actually prefer if it is a simple cloze where we fill in 31. Further more, we might actually want “type in answer” to be disabled because of how simple the reversed direction is.
