Form : Google Sheet Integration : Access to Drive Directory

Hello Team,
In the Google Sheet Integration popup, the presentation of sheet files is 'flat'
It is not possible to select a directory in Google Drive.
This function is essential because we have dozens of Sheet files distributed in our Drive.
Thanks for making the necessary.
Note : Is it possible to give a specific directory in Google API ?
In this case, what do we do if we want to access several directories for different forms?
Kind regards
