Product quantity roll up in shopping cart , multiple same items on multiple lines on kitchen slip,#957

When customer add the same item in shopping cart more time 1 time , instead of using the quantity button. the same item show on 2 seperate line. when there is a highly volume of order, the kitchen slip comes very long and the chef has no time to do the calculation and make mistakes, leading friction between staffs.

We need to have an option to roll up the same prodcuts in the shopping cart. I undestand that there are options for some dishes which make the scanrio very complex.

Can we just roll up for the product that has no options for the first step .

Great! Thanks!!
