Datetime Stamp for When Status set to a specific status.

At a lost.  Don't want to use forms, have a status field that has 9 choices, and will most likely be at least 7 or 8 of them as it goes through the process. for three the processes i have to store the date it was set to that specific status and for one of the status i have to record the person who set it to that specific status. I have tired log edit and using and creating a table to and using actions to put data in the table.  but with both i cannot get the specific information i need by lookup or formula to get the specific data I need.  Is this possible in grid edit?  thank you for any help or insight!
