legends in BEx

Dear Gurus,

We have developed a Payroll report using the data source "0HR_PY_1", the report is fine and in the report we have a column called "other allowances" which includes (HR,Telephone,joining,transport,etc etc some 10 allowances). Now if i include everything in the column heading, the heading becomes too big, so my user want a legend

Ex: in the end of the report he need something like given below,

Other allowances -- HR, Mobile, Transport, Shipment, Joining.

Is this possible in Bex?
