OptionGroup with options and checkboxes in multiple columns

I am trying to show check boxes / radio buttons in table form (not just vertically or horizontally), but let's say in 3 columns. Way I was able  to do it is by specifying style of OptionGroup as horizontal and add style that looks like below. Is there any better way to accomplish that? I had to specify style for each column as below. And I am using Valo theme. If there is not maybe this can help someone who will look for same solution:

   .v-select-optiongroup-3column .v-radiobutton {
      display: inline;
    }
    
    .v-select-optiongroup-3column .v-radiobutton:nth-child(3n)::after {
      content: "\00a0";
      display: block !important;
    }
    
    .v-select-optiongroup-3column .v-radiobutton:nth-child(3n) + .v-radiobutton {
      margin-left: -24px;
    }
    
    .v-select-optiongroup-3column .v-checkbox {
      display: inline;
    }
    
    .v-select-optiongroup-3column .v-checkbox:nth-child(3n)::after {
      content: "\00a0";
      display: block !important;
    }
    
    .v-select-optiongroup-3column .v-checkbox:nth-child(3n) + .v-checkbox {
      margin-left: -15px;
    }
