Are buttons of a enumlist possible for an action

[Arturo]

Good morning! I am trying to add buttons to select a name for an action (Data: add a new row to another table using values from this row) but the only thing I get is a list of the names separated by commas:

What I want is to choose one name with the buttons and apply the amount of the withdrawal to a balance of that specific name.

I have configured the column "student" as Enumlist (this column has the names) as follows:

Ive tried to work around this but I ran out of ideas.

Thank you for your help.
