It would be helpful if automatic item modification by age could set a date field to today's date. Example: Age in days: 60 Age field: items.itemlost_on Conditions: items.itemlost=5 Substitutions: items.itemlost=6 items.itemlost_on=Today Or, if you want to update the date accessioned to the first day it was circulating, you could set up a custom damaged status to put items in before they go to circulate: Age in days: 1 Age field: items.itemdamaged_on Conditions: items.itemdamaged=3 Substitutions: items.itemdamaged=0 items.dateaccessioned= Today's date
