Custom Train Button Location in Definitive Edition

I dunno if this was bought up or not but I think having custom training button might help a lot. Especially for Docks. We all know that we can have custom hotkeys for Techs now. I was wondering a player wants to move techs and other stuffs to the specific train button location of a production building the way they want to like I want all Dock units on first page and Techs on second page. But there will be a factory option to keep it the same way it was. I think this could be a nice option to add.
