Uninstalled Software Inventory Historical Data

For BFI, you can set the data retention for historical data (detailed here: https://www.ibm.com/support/knowledgecenter/en/SSKLLW_9.5.0/com.ibm.bigfix.inventory.doc/Inventory/planinconf/t_configuring_data_retention.html).

In that section it describes “historical data” as data related to removed computers, uninstalled software and deleted software catalog entries. Does anyone have any idea where within the application it denotes software as uninstalled, or catalog entries as deleted?
