Terminal Strip DWG Configuration

I've been having issues with naming convention on terminal strip drawings. Every time I do multiple TS on one page, the naming convention is fit together on the page description. Does anyone know how to fix this?
Instead of 21 - 24--24+-FTB1-FTB2-FTB3, i would like it to show just "21 - terminal strip drawing 1/x" like my formula.
