Matrix conditional formatting for column total only

Hi,

For matrix conditional formatting, can we choose to which Total it will apply ? the options now is Total only but no selection to which total. Is there a trick to do so ?

Because I have format like this :

This it self already bugging me since I don't want the Row total to be coloured (formatted) also, only the Column total on the rightmost.

Then if we expand the month, it will become more 'ugly' ->

Else can I have some advice to make this report more attractive but not hurting my eyes.. 😅

Thanks,
