It would be useful to have the Batch Patron Modification "Expiry Date" field have the option to either set a hard date or "Or add number of days:", as you do with the Batch Extend Due Dates function. Use Case: This came about from adjusting 28,500 accounts this week due to COVID closures. I had to manually adjust the dates in batches of 1000 to ensure that I didn't "over-crowd" one day with too many expiring cards. Had I been able to say extend "200 days" for each account, the dispersal of accounts could have been more randomized.
+1, this would be helpful!
