Pending DD / Bacs

Not sure if anyone has mentioned this before or if people would find this useful, but maybe an option that means pending transfers are reflected in the balance.
For example:
My balance is £100 but paypal is pending (for next day for) £30 turn on this would show £70 available.
Think it would help some people with budgeting as not everyone can do math.
The sums I used were simple, but you could have 3+ pending transactions all of differing amounts.
