Library 44.1

We have some KV 8908 32" drawer slides that we need to use for a project. It has (7) drawer slide holes that need to be machined into the carcass. I've added the slides as normal and everything is working, with the exception that there are only (5) holes being drilled. I'm guessing this is because the G!LookUpTableSystemDrawerSlide look up table only has columns for the first through fifth slide holes.

So my question is, can I add two more columns to the look up table, between columns 11 and 12, and not have it break anything? Or at least, not have it break anything for this one project, since we won't be using any other drawer slides than the KV 8908?
