Enhance CSV Exports / Allows User to Select Fields to Include in CVS Export

I would love to have the option of exporting all my budgeting data as a csv.  This would be transactions but also details on budgeted amounts and sinking fund totals.  It would be great if we could get some functionality to customize these csv exports to the fields/data we want.

Implementing this would also improve the feedback we can give for overall analytics and insights.  I can sort of visualize what I want but being able to actually pull down the data and then play with it will let me lock in what analytics are helpful for me and maybe for others too!
