Hi Natalia,
This functionality does not currently exist within Attendee Hub, but I definitely recommend upvoting this idea on the Product Ideas page that was submitted by another Cvent user: Using Seating feature in Event App
As a potential workaround, you create an internal information field for Table Assignment and then import the answers for their assignment and then configure this as an Attendee List filter so that this is able to appear in Attendee Hub (reference step 3 of Configuring Your Attendee Hub Attendee List) for more information on how to configure this.
