more values for variable

Question

i have the problem that i have to manage the values of an dropdowm-field.
if conditions 1 = value 1
if conditions 2 = value 2

but if condition 1 = true and condition 2 also true the dropdown should have value 1 and value 2 to choose (the real formular is much more complex)
How can i define in the "data builder 2" that the value is added to existing values?

I hope i explained the problem clearly enough - my english is not the best

Could do it in PHP. If it's a {var:} then you would do​$this->set('variable_name', $this->get('variable_name') + ['new_key' => 'new_value']);
