Help to save data in bulk

Hello guys, I need some help

I have a list of users, and for each user I need to record information from another data list (in this case they are days, but using the text property, I have 30 lines representing the day of the month.

I managed to create a boron to save just one day a month for the user.

Screenshot of ScreenFloat (24-06-20 05-56-27)

I liked with a touch of the button, saving the 30 days (30 lines in this case) on my user.

That is, I need that when I touch “a button” several users are added in the “name” row, in the user column at once.
I do this, but only one at a time, using the update table, row and column function.

Can someone help me?
