Prevent logon dialog when importing into Sandbox

Hi,

I am trying to import a change document into a sandbox system in Charm.

I added the action TR_SBOX_WEB to the status it should have when the transport is successful.

I added a task in the tasklist of the sandbox system: /TMWFLOW/SCMA_IMPORT_H

When I try to set the change document to next status, it indeed starts to process the sandbox transport, but there are several interactions with the SAP GUI.

1. I need to select the Sandbox system from the available systems (all target and production systems in the logical component are presented)
2. I need to logon several times on the target client and on the Charm system (more than 2 times each, haven't figured out the right number and sequence yet)

Is there a way to prevent that interaction?
