Stock level of current box open

Prior to eMar, we would count the stock of a current box and mark it on the paper MAR after each administration. This made stock monitoring very easy. On Atlas, however, the total stock can be 240 tablets and no one is going to count through all those tablets after administering one. My suggestion is that there is also an option of 'current opened box stock level' so there is less stock to check at a time i.e. only 27 tablets in current opened box and 210 tablets in backup cupboard.
