Need Help adding tuning to a toddler bed

I wanted to add Claim Bed/Assign Bed to toddler beds and crib. So I tried to find the tuning files for single beds and found: interaction/SimPicker_Bed_AssignSim & interaction/bed_ClaimOwnership. I tried using MizoreYuki's & Bakie's Tuning tutorials to add them to the Bland Co Toddler bed but the interaction/option didn't show up in game. Though I did realize it was probably because I didn't change the Object Definition Tuning Name and ID with the new ones but I also realized that doing it that way would mean only one Tuning file would be used and I also think the Toddler bed options wouldn't function anymore because the tuning was from a single bed. So now I'm stuck and don't know what to do. Does anyone know?

Here is the test file:
