Yes, you can.

In each influencer profile, you will find a envelope with a small heart at the top left. When you click on it, you can select which campaign you want to request this influencer for.

Furthermore, during the application phase of each campaign, you have the button “Request Influencer”. If you have already created influencer groups, you can request these for your campaign during the campaign creation process.

Note: A request does not necessarily mean acceptance. The influencer is not obligated to accept it, and you as the brand have the option to deselect them.
