Using AirDrop to copy Folders into Goodreader

I manage a Song Book for my Ukulele club which has 400 songs. I have it stored in a folder in GoodReader on my iPad. When a new member joined in the past I would use Airdrop to send the folder to their iPad and a dialogue would pop up and give that person a choice of where to copy it into including GoodReader on their iPad. But now no choice is given and it just drops it into Files. And there is now way to copy or move a folder from Files to GoodReader. Is there anyway to get this choice back?
