SLT Connector: How to stop and restart pipeline without losing subscription?

I'm creating the following Data Intelligence pipeline. A STL Connector pulls data from S/4HANA and the data will be converted to CSV. Here I'm using S/4HANA's embedded SLT.

The SLT Connector is configured with transfer mode "Replicate".

When I run the pipeline, a subscription is registered at S/4HANA side as below, and all the initial data is transferred.

Now, suppose I want to change some configuration in the pipeline. To do so, I would stop the pipeline and restart after making the change. After restart, I want to replicate only those records modified while the pipeline was down and thereafter.

However, when I stop the pipeline, above subscription is removed, and a new subscription is registered as I start the pipeline . Hence, the pipeline transfers all the record as if it is the initial load.

How can I stop and restart the pipeline without losing the subscription?

Best regards,

Mio
