Need feature to combine To Go orders

There is currently no way to combine or merge two or more TO GO checks into a single check. There are multiple scenarios where this need can arise. The only way to do this now is to open each check  and move each check to a table. Then merge them and change them back to the to go order type and pay the check out. I have had nearly every merchant complain about this more than once. We need a "merge" option on the TO GO orders like there is on the table layout screen. Thanks.
