Invoice Batching through iSupplier Portal

Hello All

We are considering iSupplier module for implementation in one of our geographies. We currently use a 3rd Party e-payable solution there. However, one of the features which is very important for us and which this 3rd party software provides is invoice batch grouping. We have thousands of invoice come from vendors everyday as we are a big manufacturing company.

Does iSupplier provide any invoice batch grouping feature in standard or work around way? Is there a customization one has done before in iSupplier which provides invoice batch grouping?

Thanks

Roger
