Currently, if you create a pivot table where some cells contain lists of items, then export that table to Excel, each list is contained in a single cell which makes manipulating individual items in the list hard (i just spent 30 minutes individually converting cells using Text to Columns on each with Ctrl J as delimiter, then transposing the results back to vertical lists, then pasting back into the table. Ideally it would be possible to have each item in the lists occupy a single cell, with the row titles in multi-row merged cells.
