Is it possible to skip the 2X application connector?

I would like to use 2xa files without providing the passwords, the passwords will be introduced by the user the first time that a session with a terminal server is opened (by executing a 2xa file) and later on if a user wants to open a application on the same terminal server they will reuse the opened session and the password should not be reentered.

All works quite well except that the 2X application connector windows opens constantly every time a 2xa file without a password is executed. This means that I log in with a password, close the application (the session is stil open) and if I execute another 2xa file the 2X application connector windows opens and ask for a password, if you do not introduce anything and just click the connect button the new application still opens using the already openeded session, therefore the window makes no sense and I would like to skip it.

My 2xa files looks like :

<App xmlns:dt="urn:schemas-microsoft-com:datatypes">
<Connection>
<Port dt:dt="ui4">80</Port>
<PrimaryServer>158.226.232.276</PrimaryServer>
<StartMode dt:dt="ui4">0</StartMode>
</Connection>
<Logon>
<Domain>Domain1</Domain>
</Logon>
<Startup>
<PublishedApp>Equipment Explorer</PublishedApp>
</Startup>
</App>
