As an example, consider a grid analysis distribution. 

To combine the items, click on properties.

Properties pop-up will open. Click on 'Items' tab in order to combine as attributes cannot be combined.

Clicking on combine will add a new variable called 'New Combination' (highlighted in red). 

Double click to edit the name of the combination. User can also delete by clicking on the cross icon.

Click on Set will apply this combination and will display the combination scores as Top 2 for 'very satisfactory & Satisfactory' in the analysis table as highlighted in red.
