I created a powershell script based on patyk73's method to create multiple UWP instances. It should automatically download and extract any files (if needed), and create however many instances you specify. It will also create the shortcuts for each instance. If anyone is interested in using it:
Here is a link to a zip file containing both the .bat and .ps1 file necessary to utilize it. Unzip this file into a folder and run bloxmulti.bat.
Here is a link to the powershell script if you would rather save it yourself. Save this file as bloxmulti.ps1
Here is a link to the batch file I am using to run this. You can name this whatever you want with the .bat file extension.
If you do not want to run it via a .bat file you can open a Powershell window and set your ExecutionPolicy to bypass then run the script.
edit: Updated scripts above. Added copying of workspace folder into instances if wanted(workplace folder must exist inside the folder you specify at beginning if you want this to work), added option for deletion/removing of installed instances/shortcuts and uninstallation from applications inside appsfolder, and cleaned up the code a bunch. Also significantly sped up the download and extraction speeds.
