You actually shouldn't really try to work around the new (and stupid) QB restrictions in this particular case, where you would be actively paying the same employee twice per pay period using two employee records. That can cause all sorts of problems.
It is much better to create two paychecks for one employee record in the period, if for some reason you must do that. Things still won't be quite right, because the Federal and State withholding amounts will be under-withheld unless you actively manage the situation. Which makes you non-compliant.
Why do you need to create two paychecks? I am having a hard time coming up with a case where that would be required.
