How to transfer sale-price, sale-start-date, sale-end-date

[Lemodo20]

Hi,

in old MWS Flatfiles i can transfer above fields to amazon. But new specification don't allow them any more.

So my old file looks like this:
TemplateType=Offer Version=2014.0703
sku price quantity operation-type sale-price sale-start-date sale-end-date leadtime-to-ship fulfillment-center-id

new Flat.File.PriceInventory looks like this:
sku price minimum-seller-allowed-price maximum-seller-allowed-price quantity fulfillment-channel handling-time

so this 3 fields are removed.

How can i transfer now this 3 informations. I don't find other flatfiles, which contain this fields.

The standard item feed template still contains those. (using partial_update)
