XL 2016 (non-o365) and Win7

I am using PowerQuery in Excel to pull data from an AD server. Bear with me as I have not dealt with PowerQuery for years (and it was always my weakest XL skill). I have most of the fields I want from the query, but want to create some "Calculated Fields", which appear to be called Custom Columns.

What I specifically want to do is take the "userAccountControl" column in the Power Query editor, which contains integers (table can be found here) and convert them to binary values. However, every attempt at creating a custom column I have made fails at this. I have tried using various "Binary." functions from here but they all give an error stating that they could not convert the decimal value to binary. I get the same error if I instead set the data type of the column to binary.

I am a little frustrated as I feel like this should be a pretty simple thing to do but I just cant find in my research any viable examples of this being done (excluding results proving code blocks that may accomplish this). I already have a worksheet formula I have written that accomplishes the goal for me, the problem is when the main table in Excel the query dumps to is refreshed my added column is removed with the sheet formula. I am reserving sticking this option out in the event that this cannot be done simply in PQ.

Any guidance would be great, if need be I can provide more specific descriptions, samples, etc. Thanks
