[Koha] Modify Patron Transaction Invoices and Fee Receipts

[Ms. Naveen Ali]

Dear members, 

I'd like to modify the Patron Transaction Invoices and Fee Receipts. 
In fact all the print options available on the Patron Screen (Summary, Slip, Quick Slip, Overdues, Check In Slip) 
I can't identify them in the Notices and Slips Tool 
Please provide support. 

With best regards, 

Naveen Ali
