Input file options?

All of our actors use input files for creating lists of urls to scrape. Up until now, we have been using a "publicly available" folder on our network with a personalized Web server in order to make the input files accessible to Apify. However, in our new network, we are experiencing tremendous difficulty replicating the permissions of said Web server. I know that one option is to upload input files to an S3 bucket, but we would prefer not to go that route at this time. What other options exist for making input files accessible to actors stored on the Apify platform? Any ideas would be greatly appreciated. Thank you!
