I want to add layout number to each layout in the print composer. I've cant find a variable with that information in it that I can access from the expression builder.
Generally our projects are built with many single page layouts. They need a unique ID per project, but this ID can overlap with other projects. So I figured we could automate away the task of making sure each layout has a separate ID number printed on it, only I can't figure a way to get at the data within the expression builder.
Does anyone have an idea on a way to get a unique ID onto each print layout? (would prefer an incriminating one like 0,1,2,3,4)
