Aah, that kind of filter. 😞 There isn't one, unfortunately. A random tip I have for you is to use Ctrl + F on the browser and search for the Project Manager's name. Given that the system only shows deleted deals for the last 90 days, I hope there shouldn't be many for you to go through.
Also, when you say that you wanted to send the restored deals to a dashboard, do you mean a dashboard for the restored ones or for them to go back to any dashboard where they are relevant along with deals that were never deleted?
it seems to me that you might not have enough permissions to restore deals. The restore deals section has the date range and the search button next to it. Do you mind me asking what subscriptions you have?
