Link Commentary Set

I have downloaded the NAC series (one of my favs) to a small laptop and would like to set the link set to "A" for all the volumes, so they will track with the ESV that is my preferred Bible. Is there a way to link all volumes at once or do I need to open each Bible book and then link that commentary to it?

You only need to link one commentary from the series. Moving the bible to a location in another bible book will automatically switch to the NAC volume of that book and will retain the link set.
