Add Group Levels using Better Chat?

Could someone give me an example of how to add the group modifiers in this so they coincide with the Better Chat Groups.  Right now I have ex. VIP, VIP1 and VIP2.

"Group_Multipliers: {
	"Default": 1.0
},

Would it change to just:

"Group_Multipliers: {
	"Default": 1.0,
	"VIP": 2.0,
	"VIP1": 3.0,
	"VIP2": 4.0
},

Again, this is an example, but would it be formatted the same?  Or would I need to add something like "betterchat.VIP": 2.0,   etc..

I may have found the solution!  It appears my config file for the plugin had all the code removed and contained a single word.  "Null."  Lol, I deleted it and reinstalled the addon.  Will let you know the results.

and did it work?

we search for a solution to make all kit-groups from our shop to bring them all in better chat group "VIP",

so that we have in better chat only group default, vip for all players buying a rank-kit, admins and mods
couldnt find a right solution, especially to make this automatically

the rank-kit groups were made with admin menu.

we got no rank-groups in oxide.config, only default, moderator and admin
