Event Manager Multisite – How do I share posts to sub sites?

Hi,

I want to share Events over the Multisite Network over categories Combbined with Shortcodes and search tags. I already got Events from sub sites to the Main page. This works fine as you can see here: http://www.heliand-pfadfinderschaft.de/veranstaltungen/

But the Events don`t appear on the sub Site. How do I share them to the subsites? Can I somehow use the same Main-Site-Database from every Sub Site?

And then I could sort the Events with the shortcodes.

I activatet the global tables.
I hope someone can Help me soon.
