I am putting together a book, which isa 3-column task planner (blank) like a journal. So the pages are lined and formatted with headers and with spaces where folk write their entries (tasks, jobs etc)

It has a) one facing page with 3 labelled columns for writing tasks in and B) a second facing page that is for notes. This forms a two-page spread.

I want 90 of these two page spreads to form a " blank" 180 page journal.

I want to be able to quickly copy the original two-page spread 89 times.

Is there an easy way to do this, keeping the page size (9 x6), columns, formatting and allowing header pagination etc
