Using a "grid" import for multiple PO Receipts?

Has anyone created or attempted to create a customization that would provide a user interface where an Excel file containing multiple rows of PO Receipt information could be used to generate multiple receipts based on a PO Number being associated with each row?  Basically, a grid interface like is typically seen in various components of Acumatica wherein a “user” simply imports the desire info.  This would alleviate the need to use an import scenario, which we do not want most users to touch.  It would be a tremendous efficiency gain for those processing PO Receipts.  Currently, my users have the worksheet and they have to split the information out into separate files to perform the grid level import for each individual PO Receipt.  I’m hoping someone else has thought of and created such a customization.  I’m too new to Acumatica to create what I believe is a more complex customization.
