Showing Text for months using LOV

hi guys

I want to see month and month number in my lov togther is it possible if so how? For example my LOV should show JAN and "1"  when i refresh my LOV for a month dimension.

I have 2 dimensions in my universe (Month Code and Month TXT). One shows the number "1" the other shows the text "JAN". How do i combine the 2 into on LOV for one dimension Month.

Regards

Adnan
