Copy to new recurring receipt
All you have to do is divide the instalments manually (like here 2000 in 10 installments each installment of 200) Manager wont do that for you and just calculate the no of weeks/months and end that recurring receipt there, it will automatically stop.
There is one more thing which would be nice to have is Scheduled Transactions. That would serve as a reminder too and when that transaction actually happens you can create/post the transaction with just a click. (Using recurring transaction for 1 time could do this but that leave the copy of that transaction in the recurring transactions too so you have to delete that manually)
