Сan I create a sub-group for headers that will not create a new line from above but occupy part of the grouped headers instead?

Question

To better explain what I need, I added a picture. I want to get option 1 instead of option 2 which is usually created with column var1 ("Title for both vars" var 2 var 3) var4

The only thing I came up with was creating subgroups also for other variables and then distributing text between the "subgroup" title and the defining title like:

`column ("part1" var1) ("Title for both vars" var 2 var 3) ("part1" var4)
define var1/display "part2"
...
define va4/display "part2"`

But it looks not convenient at all and I am sure that there should be a more logical solution but I can't find it
