In that case, what you need to do is assemble a variable with all the names you want by repeating an If/Then for each. Here's an example:
Paste Names via Checklist.kmmacros (4.0 KB)
Although you can't see it in the image, please note that there is a line break after the names in the If/Then actions to ensure that each name gets added on its own line rather than all on the same line. I also used a local variable for "NamesToPaste" because "NamesToPaste" needs to start fresh every time this macro is run, or else you'll end up with repeats and doubled names. If you haven't yet upgraded to KM8, you'll need to make sure to set "NamesToPaste" to %Delete% at the end of the macro.
