The Neo Store client for FDroid allows you to do this. I haven’t actually used the install feature yet, but it exports a list to an .aps file and says it will load and download the list (dependent on the repos you have activated.)

There actually is an F-Droid repo now for Ironfox, which I think I accidentally found in the repo list of NeoStore (another F-Droid client.) Link is also on gitlab:
