When searching for a customer Invoice in "All" invoices open screen which then brings up all Invoices under that customer you then click on a Invoice you want to open. Once opened, you then want to look at another Invoice under the same customer but when u "click back" ALL Invoices are listed again and you need to search for that customer again rather than just leaving the searched customer invoice listing on previous screen. This process or searching has to be completed each time you want to search Invoices from a specific customer rather than leaving customer search on previous screen.
