There are tables within the Smart IT database SmartIT_Business.PREFERENCE and SmartIT_Business.PREFERENCE_DETAILS where it looks like these console filters are saved, but I haven't tried playing around with adding them directly. Play at your own risk
Would you kindly paste snapshots of the tables in the SmartIT database? Would be much helpful.
The below BMC doc should help on understanding where the Smart IT filters are stored -
Please be cautious on makes changes to this and BMC suggests not making any changes to this unless you have a huge Business need to do so and there is a risk of losing those change on each Upgrade or Hotfix you apply to Smart IT.
Hope this helps!
