Loan account / bill payments by lender

Many of my clients’ bills are paid by a 3rd party/another of their companies as a loan.

Currently, I record this as follows.

I’ve created a Liability account “Non-Current Liabilities - notes payable” for that 3rd party (Lender).

for each bill they pay I create a journal entry to credit this liability and debit my creditor-supplier.

I then match the journal entry with the bill to show the bill as paid and by that lender.

This is a very long and tedious process, being that I have many such transactions. It also leaves a more complicated trail.

Can anything simpler be done to make that liability account work more like a “Line of credit” except that in my case it is a long term/Non Current liability whilst the Line of Credit option is only available under Current Liability.

Thanks, Lee
