No, you can't.

What's a  tick mark ?     

Curiosity killed the cat....but satisfaction brought it back.   Please bring me back.

Lacerte allows a "tick" mark aka audit check mark on the returns.  

You can use is to "mark" that a number has been reconciled/reviewed/is correct.  If the number changes, the green (as in the number is correct) check mark changes to red.

It is a GREAT feature IMHO.

Thank you.   Sounds like it would be a nice feature for ProSeries.
