"Texture streaming pool size" Save Increased MB Value?

So I’ve been getting the “Texture streaming pool size” warning message on a project I’m hoping to sell on the Marketplace. I’ve Increased the value to 2000 using the “r.Streaming.PoolSize 2000” command which fixes the prob, however each time i restart the project i have to re-enter the command. Is there any way to save the increased value so I don’t have to keep re-entering it and will this affect acceptance onto the marketplace?

You can add a blueprint node which executes this command on every play

Or you can go to Edit → Developer Tools → Device Profiles and set up the right one with your command. Also have a look at:
