Stealth Paypals, Activity Allowed with Bank Addition?

[MaggieMae]

so with this new PayPal account process now, obviously i am not going to switch my stealth accounts to Cash Paypals, but if I add a bank to a stealth account, then...

1) will my invoice payments automatically go into my bank, each individual invoice payment or will I be able to do a transfer of a larger lump sum, from several smaller invoices ?
2) and shipping from stealth paypal multi-shipping, when i make payment for a batch of ship labels, say $80 for that day, I am probably given a choice of payment method, which would be either the VCC on the stealth account or the attached new real bank account. I want to continue to use the Paypal multi-shipping option for ship labels, not for ebay orders, just entering addresses, not necessarily the invoices done that day, just entering info for shipping labels, like I used to. All depends on how much $ in what account etc. Anyone have experience doing the multi-shipping on Non-Cash paypal account with real bank attached, without shipping ebay orders or straight invoice process?
Thanks in advance.

I cannot answer 2), I've never used it.
1) I manually transfer several smaller payments in one withdrawal transaction.
