[Koha] Patron Card Creater-- Export as CSV file

Dear all: i am using the label creater and patron card creater, just wondering that --- in the label creater, when we export batch data, there are 3 options that we can choose ---which are (1) Download as PDF (2) Download as CSV (3) Download as XML However --- in the patron card creator, there is only 1 option, Export as PDF file. Would be possible that provide one more option here , Export as CSV file,to let user to choose from? This option will be very useful to our use case. Any help will be appreciated. Thanks!! Sincerely, Jiahui
