Another Suggestion I've just remembered is, are you able to check what version the profile has (standard, EOD etc) and hide the storage quests from Warden if you already have the upgrade from your edition
There is no easy solution for auto-complete Hideout Assistant quests like I do for Gunsmith Assistant. In theory is should be possible to inject code that will run after raid is completed, check for already build stations in hideout and auto-complete quest if corresponding station is already build - this is not only about stash but about any hideout station is you choose to build it before completing corresponding quest. I have no done codding like this before, so unable to give estimate when it will be ready or if it will work, but I have plans to try at some point. Meanwhile you can use profile editor or manually change quest status to "AvailableForFinish" to complete quest and get reward
