How do I do this with my custom pages? (need a time saver)
 

I have my custom pages working they call to templates in the scheme the user is using, how would I make it so it calls to one template in one scheme which works in all of the schemes? Its hell to update them all, and It would be easier than having to change multiple templates in multiple schemes.
could anyone give me a solution?

Adding a template to the Master Style will add it to all styles on the board. You can then just edit the master style template or move all the styles to a child of one style and then just edit the template on the one style.

when applying them all under one parent scheme does it change any templates when I move them or not? Thats what I'm worried about. Thanks for your reply.

I don't understand what you mean.

When you put a scheme as a child scheme to another scheme it says all templates updated etc. I dont want any templates to be updated when I asign a scheme to a parent scheme because a bunch of them are coded differently.
