I would like to be able to add a tag to multiple entries within a subscription at once, for example put a 'TEST' tag on all entries within a test subscription.

During the renewal process around an EA contract it could happen that customers get a new EA number. Azure Costs should offer two the option to archive and merge an EA contract into a new one.

The archived EA will not synced any more and no daily e-mail reports will send out. The merged one contains all the historic information so a seamless spending management of the migrated subscriptions is possible.

Cost monitor is able to see the daily expenditure of a subscription, so it should be able to automatically calculate some kind of baseline. With this information it should be possible to send out an email alert if a subscription is spending a lot more money all of a sudden (because somebody left 10 big test VMs running for example).

The dropdown box for selecting just a single month is not enough. It would be helpful to make the timeframe selector for costs analysis infinitely variable.

Currently the budget difference between one month to an other is not detailed enough in the chart. A very helpful extension could be rendering the difference as a percentage value between the bars in the chart.

Currently when hovering over the different chart elements every subscription related item is highlighted but it's not possible to click the item. It would be very helpful when the click on an item opens up the correspondent subscription.
