New option on deploy chart on Rancher UI

How can I add a new option on “Helm deploy options” in th Rancher UI??
I need add the “–atomic” option but I have no idea where it is configured.
By default it shows the options on the picture above

Yes, I am having a similar problem here. The documentaion says there should be some yaml editor available for editing:

but I have no clue where the editor is to edit helm options. Is it hooked somewhere else?
