Google spreadsheets sheets control

How can I create new sheets within a google spreadsheet in my app? I want it so that the user can click a button to create a list and name it which corresponds to a new sheet in google spreadsheets.

Or is there an app inventor addon which allows for easier control of spreadsheets?

Any help is greatly appreciated
Thanks!

Wouldn't you rather just add a column to your sheet identifying the user, and just add new rows to the table identified by that column value?

You would need a google apps script to create a new sheet/grid inside the spreadsheet.
