Select all graph-table column values

[#1]

I’ve a Graph Simple Table like this :

and i want that the user could select all the M.ID_SITIO of this table, without having to select, hold, and scroll through the table. Sometimes the table is about 30 lines, but other times could be more than 100 rows, and selecting all could result difficult.

How can it be done?

Thanks,

it would be easier to create a listbox or create a button that applies whatever is inside of this table as a selection

Create a list box and user can type * and enter
