ILM option to purge based on FirstArchiveDate

We have sites that only doing reading for other sites. These sites need a way to purge studies based off the FirstArchiveDate, which is not an option in the GUI. We currently have sites purging based off the study date. This causes issues when the patient brings in old studies with them to their visit. These studies sometime are past the current ILM rule. Example. We have a site that purges most studies that have a study date over 1 year. So, a patient comes in for a visit and brings their older studies to be used as a comparison. Once this study id archived in CPACS to the EA, the study is evaluated to be delete via the current ILM rule. During this time, the Rad's could be looking over the study again and creating a presentation state. This presentation state gets sent into CPACS and changes the study_lta_stat to "I" and also changes the acq_stat_changed_dttm to the date that the PS was created. Then 8 days later (AutoArc Task) the study gets put into the archive queue and can't be processed, because the lta_stat on the image level is "D". This is causing extra work. Either we get traps for archive queue or customer needs to merge an exam. Then we have to log into the EA and put the patient on hold to clear the lta_stat='D'

This process can be done via a powershell script, but you can't evaluate the study list. This is we we need to add more options in the GUI like FirstArchiveDate to help customer configure ILM to meet their needs and reduce service work.
