Can you create a search with Items, Purchase Orders & Sales Orders ?
Do an item seach that uses columns (and probably filters) from the transaction join. (joins are the options at the end of the column or filter options with `…` at the end)
The opposite transaction search that uses the item join may also work for your purposes.
I hope this will helps you,
These are the products they have Transaction: Sales Order.
If I may to,for this type of Saved Search better use Transaction Saved Search not by the Item.
