Work Schedules for different Groups

We are working with Wrike to connect our international Teams. I have several Groups in 4 different locations. It would be great to have automatically the public holidays of a City / Country in Wrike. Today I have to add all public holidays for 4 Locations in to the 4 different work schedules by myself.

I take the public holidays from a website fir Germany (Hesse), France, HongKong and China.

In Addition I would like to Publish these public holidays somehow visible for the full team (for example in calendar) without creating anything double
