Custom Command Line Parameters confirmation cancellation.

Hello, my request is simple:

When using Session type "Command Line (External Application)" there is a way to add command-line parameters under Parameters tab. Those parameters can then be used on General tab. Combined, you can set both names and values for parameters. However when you start configured session there opens a popup window named "Custom Command Line Parameters" which allows to change set default values of said parameters.
I'd like to have a way to skip this window altogether when opening sessions, preferably by default and/or by a checkbox on Parameters or General tab.
