Again, you have to do this manually using your own text layers and expressions to adjust transparency.
I guess you would start with an expression for the day value of the next day, maybe:
using the tag: #DOW# - Day of week int (0-6 where 0 is Sunday)
where next day = ((#DOW#+1)%7)
So, 7 text layers ( all centre aligned and with same X and Y positions ) where
"Sun" Transparency given by: $((#DOW#+1)%7)==0?100:0$
"Mon" Transparency given by: $((#DOW#+1)%7)==1?100:0$
I hope it helps.
