I have community builder and virtuemart installed on my website.
I disabled Joomla user registration as suggested in the CB documentation, to have all protected area of my site run through the CB registration process.

When in the virtuemart shop, and I want to check out, I get a message 'User registration is disabled, it must be enabled in order to proceed.'.

When I enable the joomla user registration I get the returning customer or new customer screen, as expected and as wanted.

When I leave the joomla user registration disabled. First login and then go to the checkout process, i goes as I wanted it.

Is there any way to have the users run through the CB registration, without first having to logon and then go to the shop? In fact at the checkout process step of VM.
So that it runs a bit more smoothly in one place.

Because I have a feeling if they first need to pop out out the registration, login and come back to the shop, I might loose them.
