Grade totals for individual assignments

Is it possible to set a point value for individual assignments and have those be calculated within the same column (WITHOUT needing a separate calculation column)? For example, I would like to be able to create an assignment worth 20 points. Then, I'd like to see a percentage calculated from the score I put in within the same cell. So maybe a cell would read "18 (90%)". Is this possible?

Hi Nathan,
It isn't possible at the moment without creating an additional column.
Noted your request though! I'm sure that will be useful for other users as well.

Thank you!
