Enigmatica 2: Expert v1.82a
Minecraft Forge: 14.23.5.2847
RFTools: 1.12-7.73

I know 1.12.2 is probably getting phased out, but it's also a request for newer versions. Also maybe this functionality exists already and I just haven't seen it yet!

I'm wanting a block that can be used to set the owner of a Powercell. I have a system that places and breaks a Powercell that I haven't touched so it says Owned by: [Minecraft]. I'm imagining this new block would take the name of whoever placed it, so if I placed it on the ground and pumped Powercells through it, it would label the Powercell "toastonrye" instead of "Minecraft". I'm not sure however if there would be any security implications with that idea though...

I have tried to make a concise video (3 minutes) explaining my issue: https://www.youtube.com/watch?v=ay60IR6101g
There is also an issue with the Actually Additions Phantom Breaker I believe where it erases the inventory and data associated with the Powercell Ellpeck/ActuallyAdditions#1350 .
