Storyline: inserting screen captures in a single slide

Hi Heros!

I'm a newbie so thanks in advice for your support.

I need some help to solve this scenario.

I have a storyline file where i defined the course structure in which I would like to insert some screen captures recorded separately, always with Storyline, in other .story file.

This screen captures have been saved as "Step-by-step slides" for editing needs.

Now, after editing them, can i convert in "Video on a single slide"?

This would allow the display of the slide as single.

I know that I can do that also by Player menu, hiding from menu slides that I don't want to be seen, but inserting as a single video can also allow me to have a single seekcontrol bar.

Do  you have any suggestions?

Thanks a lot.

Ale
