Scheduled Transactions

[Kris]

I have about 75 customers that I invoice on a monthly basis.  It would 
be much easier if I could just set these monthly invoices up as 
Scheduled Transactions, but, while the transactions/invoices do appear, 
they aren't linked to the customer and I can't edit them.  I also can't 
get rid of them, so I have hundreds of dollars of invoices for unknown 
customers.  :-D

Is there a way to do this?  Thanks!
