CWS InApp purchases and recurring payments

[Edwin van der Sanden]

I have published a free extension on the CWS and I want to add  2 subscription types as in-app purchases ( professional and corporate edition ) . I would like to sell these as monthly subscription but as it says on https://developer.chrome.com/webstore/payments-iap#inapp-buy

 Note: Recurring payments are not currently supported through the Chrome Web Store interface. 

Is there a way to upload the SKU details of a InApp subscription at all? What are my options?
