How do I make every x seconds start from the beginning of the game?

I want a few sprites to spawn every ten seconds, but I don't want to wait ten seconds from the start of the layout before the first instances spawn. Is there a way to make the first loop happen right at the start of the layout and then after ten seconds the next loop begins and so on, without waiting ten seconds initially without anything spawning?

Transform your spawning actions into a function.

Call it on start of the layout and call it also every 10 seconds.
