Choosing Multiple Selections

[gatorfe]

Hello, we are running powerplay 7.3 and have some powerplay reports created for users.  They were created several years back and almost all have been moved to Cognos 10.1.1 Analysis Studio.  On one of the ones that have not been converted yet a user is trying to find out if they can choose multiple qtrs like the attachment shows versus just one to do a comparison between the two specific qtrs?  Is there a setting we can turn on or off to be able to do this?  Thanks in advance for any suggestions!
