Here's my inelegant solution:
1. Created a tab after the notes tab.
2. Add a table to it with the fields, Period, Month, Descr and Date.
3. Name this table Periods_Table
4. Current Period and Current Year fields are in the report sheet in cells B6 and B7, respectively.
5. Formula to generate the report title is,
=""For the ""&VLOOKUP(TEXT($B$6,""00""),Periods_Table,3,FALSE)&"" Ending ""&VLOOKUP(TEXT($B$6,""00""),Periods_Table,4,FALSE)&"" ""&$B$7
Like I mentioned earlier, it's a little tedious to set it up but it works.
