Find Lowest Column Among Several
 

Say I've got the line

Set objProduction = objCurrent.Worksheets("ACCOUNTS").Range("A4:F600")

in code. On the worksheet "ACCOUNTS", the last entry by the user might be in
row 23. However, it may be in column A, or column C, or column E.

Is there any way for Excel to detect that, among those 8 columns, the lowest
used row is 23, and then resize the range?
