LUT-LBX in RA2 Inclusive v7.6

I am currently working on a project that is using some 1 watt LED fixtures for step lighting. There are circuits with only 2 of these lights per 6NA device. I was wondering why the software does not let me use the LUT-LBX interface and add it to the BOM automatically. Am i missing something or is that feature just not in the RA2 software.

Any help would be appreciated, Thanks.

Currently the RadioRA2 software does not add the LUT-LBX interface when attempting to assign a wattage that is less than the supported wattage of the device. We have passed this feedback on to the development team.
