Different Paypal Accounts Depending Of Cart Value.micropayments.

I use micropayment on paypal as most of my sales on ebay are less than £10.

On my website I will hopefully be getting in larger amounts and it would benifit if those orders went to a normal rate paypal account.

My question is can the paypal payment be switched when the total goes over the £10 mark. I had a look in setiing for payment but did not see any.

So to sum it up if a toal is less than £10 it goes to paypal accoun “A” and if it's over £10 It goes to paypal account “B”.
