Hello Chicca,
I think there is some confusion.
I am referring to the app called Sirilic. It is a separate program from Siril.
You can find it at Siril - Sirilic
Installation etc is all explained on that web page. If you go through it you will see the screenshot also.
It has NO programming required. You just select the options you want in the interface. It creates a script automatically. You can run it or if you want save the script with those options for further use.
I have used it many times for the workflow you have mentioned. And with ZERO programming.
Regards
