Thanks for your reply,
It took a little while to respond.
If I didn't understand it wrong, your suggestion only works for a specific one day (e.g Monday), repeating each week.
How do I set it up for multiple days (like Monday and Wednesday)? There is only one option to set the availability date in the product configuration.
I have accomplished to set the availability of product "A" on Monday repeating each week, but I am not sure how to set the availability also on Wednesday.
I added the screenshots of my configuration as attachments.
