Dear fellow members,

I have a huge >250 slides powerpoint (Master ppt) for full presentation. But then, I may not always have time to do full presentation, so I need different version powerpoint for 5mins, 30mins, 1hour, 3hours presentation (using only part of the Master ppt).

Currently I have 5 different ppt files (5mins, 30mins, 1hour, 3hours, full presentation), which is difficult to manage. One small update, will have to be done in all 5 ppt files manually.

a) What is the best way to manage ppt for different length of time?
b) Is there an automatic Macro function to hide/unhide ppt slide by clicking a button (buttons: 5mins, 30mins, 1hour, 3hours, full presentation)?
c) Can powerpoint automatically update all 5 ppt files once the Master ppt is updated?

Many thanks.
