Yes, you can restrict the deals a merchant can see by Deal Status.

An administrator can setup this restriction in the Admin pages under Account Configuration and a link to merchant portal settings page.

On the settings, choose the Deal Statuses for the Deals you want to show up on the Merchant Portal. By default, no statuses are selected and all deals will be displayed. To select more than one status, hold control down and click multiple statuses.  When done selecting, click 'Save'.

Only deals with those selected statuses will display to the merchant user on their portal. 

These status restrictions will apply to ALL your merchant users.
