Item Group Attributes Related

Item Group Attributes Related

I created a new item group and added attributes in it.
I added 3 attributes OD, Thread, Type. By entering the value slash icons is by default separating them. I want to replace those symbol with my own.

For example, group name is 'male connector' and values of attributes are 8mm, 1/2", BSP.
Item name generated is male connector- 8mm/1/2"/BSP.
Whereas I want to display it as male connector- 8mm x 1/2" BSP.

I want such feature to make my own display style. Please provide update for such.
