Interrupt animation play black

OK, so I am using Synfig as a presentation tool (PowerPoint just don’t do it for me anymore).

If I want to have my animation stop at certain points (to wait for my mouse click to continue), the only way I can think of currently would be to create short animations instead of one big one, and use them as separate animations in a PowerPoint presentation (then I use PowerPoint as a vehicle to move from animation to animation).

Would there be an easier way?
