Hi <@&455078047180128256>,
I have seen the picture that you share in the announcement channel and I have two suggestions.
First, I think you should put the training centre in the beta version so that we can test it till the next update and see if there is anything wrong.
My other point is that I have seen two buttons on the screenshot you shared, which are save and load. I thought that in the training centre, when we create and save a training ground, the system may create a code which we can share with others to create the same training ground.
Since I have no idea about coding, I do not know whether it is hard to do these things, but I hope it helps and gives an inspiration.
