Membership Non Subscription Item(s)

So we have a great membership plugin and it has all I need except

Membership Feature Request:

Subscriptions with option for one off payment (non recurring) product - currently not available.

I also reviewed MarketPress Ecommerce but it has products, but no subscription options (like WooCommerce offers).

It makes sense that either of these plugins should offer both, subscriptions and an option to add a non-recurring fee item (like a one time setup fee).

That would mean not having to go with two checkout options for one signup...

I have seen this request for the membership plugin before but it appears the feature request was never completed. Is it going to be added in the near future.

Thanks
Mark
