Workspace Multiple users homepage set

Hello All,

We want to change the homepage of the users when they login to the workspace. We are having hundreds of users in our system & they are not aware of changing the homepage through the setting "File-->preferences".

 

Also it is not possible for us to help each & every user by doing screenshare as the number of users is quite huge. Creating & SoP is also not suggestable as majority of the users have very limited knowledge of using custom applications. 

 

So can anyone suggest a way/command so that we can set the workspace homepage of multiple or all users in a go.
