From my first use of ProShow Gold about 6-7 years ago up until my current ProShow Producer version, I have wanted (could seriously USE) a function that allowed me to insert multiple slides into a show at one time. To explain a little so folks know what I mean...
1) I create a new show
2) I create the first slide, including sizing, layers, captions, timing, whatever
3) I right-click the slide and click copy
4) I click "paste slide(s)"
5) Can choose to paste the copied 1st slide into as many empty placeholders following the slide as I choose to.
Even if I was limited to inserting/pasting 1-99 slides at a crack, it would be a HUGE help when doing projects that use a constant background with only layer and caption elements being changed/adjusted over a large number of slide/placeholders.
Honestly, I have been unable to fathom a reason why this ability hasn't been figured in since the inception of ProShow.
If anyone is aware of a way that I can easily accomplish this now (a macro someone has written that'll do it, etc) - please let me know.
