Siril 1.0.5 can Siril open multiple ser planetary videos at the same time

Hello, it has been a while since I posted here. Thank you for this great application.
I have several planetary ser videos (sequences) that I would like to convert at the same time.
Is this possible? I see a check box in the “Conversion” menu for Multiple sequences. How do I select and open more than one sequence at a time?

Hello, to add files to the conversion list, use the + button below it. If you check the multiple conversion box, you will get as many output files as input, if you don’t check it, you SER files will be merged.

Thank you Vincent for that info.
It is exactly what I need to process multiple videos.

On a side note, I cannot see how to log out of these (Pixls posts) pages.
