What documents are considered relevant for FDR?

I am the Applicant and a litigant in person. We have an FDR coming up and I am preparing the bundle. My ex wants to include lots of additional documents in the bundle, including a statement of every transaction sent to me since we bought the house 3 years ago. The thing is several of those payments were for things I paid him back for or for things we agreed to buy together. The hearing is next week and I don't have time to go through every payment I ever sent to him in the last 3 years and clarify what it was for and which ones I paid him back for. Am I within my rights to say that I do not want to include this in the bundle?

Bundles are governed by practice direction 27a. Additional documents need to be relevant and the total bundle size cannot exceed 350 pages.
Settlement will be based on needs so it's unlikely the judge will be interested in minute details of historical transactions. The main concern will be needs for housing and income. FDR is a fairly broad brush strokes approach.
If your ex insists they go in, just put them in an additional section and be clear in the section title that they are there at the request of the other party.
