How to promote a variable to global scope after saving the sequence as a workflow

Hey guys, I created a sequence and used two variables - one global (scope being Main flowchart under which the sequence exists) and one local (scope being the sequence). I then extracted the sequence as a workflow which converted the global scope variable to an argument and everything works fine. However, I now need to make that local variable as a global one but I am not able to change it’s scope now. Do I need to create another global variable, assign it’s value to the local variable value and use it as an argument or there is a way to edit the scope of a variable after having converted the sequence as a workflow?

try create an arguement in the local sequence and create an variable in global workflow. Then import arguement within invoke activity to link the variable you created.
