Use Events "Before opening" as same User as Command-Line run

Hello,

I am using a Command-Line (External Application) entry that is configured to launch an application under a different user account.

Before the application starts, I need to execute a script that performs some user-specific modifications.

I configured the script in the "Before opening" event, but it appears to run in the security context of the user who launched Remote Desktop Manager, rather than the user account configured for the external application.

Is it possible to execute the "Before opening" event script in the security context of the external application's configured user account?
