[GNC] Defered payment account

[Fred Bone]

Gnucash v2.61 on Windows 10, though I doubt whether either makes any 
difference.

I recently had occasion to sign up for a Transport for London Road User 
Charge account. (This is for tunnel tolls and congestion / low emission 
zone charges).

Under this account I get a monthly statement of charges incurred, which 
is paid off automatically one week after the statement by direct debit.

I set this up in Gnucash as a "Liability" account. However, when the 
statement came and I tried to Reconcile, I found that a "Liability" 
account does not automatically proceed to the "Transfer Funds" prompt 
window, so I entered the payment manually. (Big deal, I hear you say).

I could change it to a "Credit Card" account-type, though of course 
that's not what it is.

Is there anything more suitable?
