Predefined Text in Cells

Hi there. Does anyone know if it's possible to have predefined text in cells that only becomes visible after you type in it.

For example I label a column as frame, and in every cell of that column, I could type "GUCCI" but what I want to now appear is FRAME: GUCCI, thus the FRAME: precedes the actual name of a designer frame.

Thus will this be in custom format and how can I go about doing this.

Thanks.
