Is there a way to use focus to turn if phone line specific notifications

I use the dual-sim capability on my iPhone 12 Pro Max and was hoping the focus mode addition would solve my problem of being able to switch my work line off completely on evenings and weekends so as to be able to better separate work/ personal time when necessary.

focus allows me to turn off notifications from ‘messages’ for example but I only want to block notifications from ‘messages’ on the business line and not the personal line. Same for phone calls etc. Would love to keep using dual sim rather than going back to two phones!

can anyone help or suggest another to manage this on one phone??

thanks!!
