how to apply a border or outline to all slides in SL360

Hello

I am creating an eLearning course in SL360.  I would like to use the 'clean' theme i.e. blank white slides, however I want to apply a coloured border / outline to each slide so that it stands out against the white player theme as I don't want to use the default dark player theme.

Does anyone know how to do this and could possibly help?

Many thanks in advance.
