Hi,
If you really insist to use stacked sequence, you may try this out.
First of all, place your control(s) outside the sequence/ frame.
Create Local Variable of the control(s) replacing any control terminal(s) respectively.
As long as there is no control/ indicator terminal(s) inside the sequence/ frame, you may now Right-Click on the frame (to be duplicated) and select Duplicate Frame. This will duplicate the intended frame without duplicating the control/ indicator terminals.
Hope above make sense to you
🙂Cheers!
