Add common tag to similar transactions

Apart from tags, if we could change payment mode, category of multiple transactions at once that would be convenient and time saving.

To elaborate a bit further, let's say I have a daily expense of office coffee for Rs 20. Its not perfectly daily, but happens on most day I go to office. Now, I have been adding it as an expense for last 2 years. But, I forgot to add a tag in earlier transactions. As I duplicate the transaction every day, the tag is absent in all the entries for coffee.

So, if I could search the description (office coffee) and add a tag (office meal), I would get an estimate since inception of my logging, of my coffee expense till date.

BTW, Very handy and useful app...Love it
