Select a number of cells and update them all at the same time in power table

Hi to all.
I am using Ignition 8, and i have a power table in my project.
The new requirement of this project is to be able to select multiple cells at the same time and edit all of them at the same time.
I want to be able to select in example 10 cells in different columns or in the same column at the same time, and then if i write in example “354” all the cells are edited and get the new “354” value?

Is there any way to do this in the power table? what do you recomend?
I have worked with onCellEdited before, but it only let me work with one cell at a time.
