Apply a single signature on several items of a Bulk Select

Hello everyone to the great Appsheet community,
Is it possible to perform a Bulk Select in a (Table, Deck or Gallery view) which will open a form or a sheet listing all the rows selected so that, from the open form, the user can add "a only "signature that will apply to each of the specific lines of the items selected in the Source data table?

If so, how can i do it?
Thank you
