Need to remove extra languages from the Campaign Welcome Screen

Hello,

Running a Webchat campaign (not exactly a campaign but its the only way to get the welcome screen). On the welcome screen I am capturing the customers first name, email and language selection.

We only need 2 languages (English and French) but the drop down list provided has way more than that. Which means right now I have to create a catch-all in the flow for any selection outside of those 2 that then requires users to select their language again (this time from a shorter list of buttons that I created). The whole point of the Welcome screen is to save on some of those nested clicks and capture some relevant information into variables right from the get-go. 

Is there any way to customize that list of languages that Zoom auto-populates?
