Copy multiple elements in matrix
I'm making a thread calculator. In order to check whether user input returns a 'typical/standard thread combination' or not (e.g. UNC, UNF, etc.), I want to have a master check list matrix, probably with a vhlookup.

I'm lazy and don't feel like copying EACH element NaN...is there no way to select a bunch and copy it into the next row/column?
I can copy multiple entries and paste a nested into one entry location, but not copy them over into multiple elements.
I've seen a couple threads about using functions to make an empty matrix, but I can't quite figure it out...and really I'd probably want to make a filled matrix, and then manually edit some elements.
