my interpretation of this is the ability to enable/disable quantity, price and/or amount on each product. This would be very useful especially if I could add a date limitation (EG automatically turn off a price after a promotional period, early bird, Black Friday etc)

Thanks for raising this.. Really appreciate it if you can sort it out please.

still not a thing?

This is a must, for digital products the user shouldnt be able to choose more than one

Anyone know if this is being worked on?

Is this really not a thing?
