enable copy paste of fields between two tables AND capture the incompatible fields for correction during copy paste to avoid incompatibility.
Also, you can add "Insert Field" in grid edit and link that with table to enable addition of new fields with formulas in report mode.
Note that your AGE formula doesn't work when DOB is selected as Text 255 with calendar pop up. This is due to difference how date is input by user but there should be a fix to deal with user input errors instead of reentry of all data using another datatype.

Thank you.
