if cra slips are downloaded online, do i need to manually split 50% combined income for spouse

I have my own mutual fund and i have joint/combined mutual fund with my wife.

when I download T-slips from CRA website, I get all T-slips, my own and joint T-slips.

 

     1.  Do I need to go and manually show 50% in your percentage.

     2.  There are many slips automatically downloaded from CRA, how do I know which one is comined

           and which on is individual.
