[wix-users] Group Publish Elements on One Condition

[R]

Is there a way to group several Publish elements (under a Control) for a
single, over-arching condition versus for each Publish?

The pseudo code would be similar to a C situation like this:

if (global)
{
   if(a)
   if(b)
   if(c)
}

VERSUS

if(a & global)
if(b & global)
if(c & global)
