zoho sheet - conditional formatting - date

zoho sheet - conditional formatting - date

Hello.
I just started using ZOHO, and it seems very useful.
As I did in Excel and in Google Docs, I want to color cell(s) if the value of date is after today using conditional formatting.
but when I set 'after' I can only insert a specific date in the following field, not a saved word (as today, tomorrow, next week, etc.)

thanks a lot,
Lior.
