Permanent Background Image for WDL on Local PC

We run WDL on a local PC and have it display automatically when WD starts up. Each time we restart WD we have to go to Background Image > Load (select file) then hit Refresh to make our custom background image appear.

Is there a way to set the background image on the local version of WDL so that it doesn’t reset to white every time we restart WD? I know you can set the background with HTML on a webpage, but we can’t do that since this is the local version of WDL running in WD. Thanks!
