Avent Pump and Playtex Drop-in Bottles

I bought the Avent Manual Breast pump but I would like to use the playtex drop-ins...Does anyone have the Avent adapter that works with the Playtex drop-in system? The new Playtex storage kit does not work with the Avent pump, however, I was told that Playtex made an adapter in the past for the Avent pump...If so, I would be willing to buy it and pay for postage! Please let me know! The adapter would be much better and less messy then having to transfer the milk over between the Avent bottles to the playtex bottles! Thank you.

I don't see a way to send you a message on here.
