You can Snooze an XBert. Doing this will remove it from the Work board and place it on your Snoozed board for a set amount of time.
From the Work board, open an XBert tile by clicking on the summary.
This will open a detailed tile.
From the Action Bar across the bottom, the Status icon will allow you to update the Status of an XBert.
On the Snooze option, enter the number of days you want the item Snoozed for then select Turn On and Save.
Snoozed items can be accessed anytime during their snooze period via the Snoozed board.
Click on the Z icon in the sidebar to locate all your snoozed items. Snoozed will appear as the current Filter.
Once the designated snooze period is over, the XBert will re-appear on the Work board list to be completed.
