Where is the date of manual dunning level override tracked

Hello,

Occasionally we change manually the dunning stage at transaction level in the collector screen, transactions tab. Users need to have at disposal the manual override date in order to track which transaction levels have been manually changed and be aware when the level can increase following minimum number of days. Can someone please indicate where we can see the manual dunning level override date field? In AR R11i it was included in the form Account detail, field DUNNING_LEVEL_OVERRIDE_DATE.

Thanks a lot in advance!

Regards,
