1. Rename the game's folder to have "_old" on the end of it.

2. Start downloading the game on Epic to a folder of your choice.

3. Pause the download (It's at the lower left of the Epic Launcher)

4. Go into the folder you renamed, and cut all files EXCEPT the ".egstore" folder

5. Paste them into the same folder you selected in step 2.

6. Stop the download in Epic Launcher (It's next to the pause download button)

7. Resume the download

You can queue up multiple games this way, if a game is already verifying, you can set another to install and once it's status shows "QUEUED" you can just cut+paste the entire "_old" folder contents into the new folder. It will immediately start verifying once it reaches the front of the queue.
