Setting custom graphic for the Join Session dialogue

Often when assisting users who have very low computer literacy (users who do not know what or where the Downloads folder is), the step to open the downloaded ScreenConnect Client.exe file can be frustrating.

My request: can the graphic that appears in the Join Session dialogue that appears after a user has entered their HelpMe code and clicked Join Session be made customisable so that I can insert my own graphic with instructions for the user I am assisting?
