OE 7 seems to be lacking some very basic functionality when it comes to bank statement reconciliation. Has anyone seen a module that will allow partial payments of invoices to be imported into bank statements?

Example, I have a $1000 Customer Invoice. On 6/1/2014 the customer makes a $400 payment. It shows up in my bank statement so I import the Invoice into the bank statement and then delete the deposit from the original bank statement. When I select the unpaid invoice it automatically defaults to $1000. When I change it to $400 the icon turns to red. 

On 7/1/2014 I then record the $600 payment through the bank statement import function. 

After I do this and confirm the bank statements I see that it created the A/R entry in the journal but it did not link the payment to the customer invoice. 

I can't be the first person who has run into this problem.
