Navigate to the ad groups of your campaign. You will see two buttons: "edit keywords" and "edit bids". If you click on "edit keywords" and tick "show match types" then you can easily tick or untick the ones you need. You can also enter negative keywords in here.

Can you put Negative keywords at adgroup level, just as in Google Adwords?

The match type selection can only be done on ad group level. It cannot be applied on campaign level. The match types can be uploaded via a submission sheet but this would only have a time-saving purpose. The actual match types would still be on ad group level.
As explained above, negatives can be added in an ad group. There is a new feature that lets you enter these on campaign level as well: go to the account view (summary of all campaigns), then go to bulk edit and enter the negatives in the blank field.
Careful: This will overwrite all existing negatives on ad group level! If you want to add individual negative keywords just for one ad group, this can be done additionally on ad group level.
