Still can't access Tax Liability accts from enter bill

Clients do NOT handle Jnl entries well, it would be very useful to be able to enter the ATO BAS bill for clients just to pay and make payment against bill, but for years I have saying you cannot access the TAX liabl accts from bills, therefore clients/agents are forced to enter Jnl entries and R1 jnl entries do not appear in Suppliers to pay as a bill does.
