Bulk adjust leave balances by csv

We'd like a way to adjust leave in bulk, e.g. via a CSV upload

----------------------------------------------------

Here are two other options I'd like to suggest in addition to the CSV upload option:

_ It would be nice if we could do the entry in a table/spreadsheet style page that lists all users (and/or teams), and navigate by tabbing between fields

_ Or from a user's allowances page, hit a "next user" button to edit the next employee
