Time signatures in every staff

Sorry folks, perhaps I’m blind here …
I would like In my special worksheet that the time signature is showing on every system.
I searched in engraving options, in layout options and in the different properties panels, but I can’t find a solution.
And if write the same time signature in every new system, I get those nasty cautionary time signatures in the previous system, which I definitely don’t want at all, but can not hide.

So hopefully somebody can enlighten me in my darkness …

You need to use separate flows for each exercise. Or you can add a coda at the start of each system, hide it, and set the gap to 0.
