DataGrid2 - Edit object Next/Back button

Current we have requirement to provide Next and Back button on editing object from DataGrid2, but it's not possible to access the list from cache that is presented to user, due to all cool sorting and filtering that DataGrid2 giving us you can't create retrieve from database and do it again. It's will be nice to pass list (from cache) as input parameter to Microflow and reused it in next steps to be able to create this buttons or to have clear overview of tables row for easier creating of logic for Nanoflow with JavaScript action currently you don't have anything (just adding simple auto increment indexses).
