When a LiftPlan is open, the button "Convert to Tieup" is available. When clicked, you are prompted to save the newly created Tie-Up version under a new name. TempoWeave defaults the suggestion to the current draft name with "-TU" added to the end.

In this LiftPlan:
LiftPlan before Conversion
After clicking Convert To TieUp, the draft will now have as many treadles as necessary without pressing more than one treadle at once as shown below.
After Convert to Tie-Up
If you originally have a LiftPlan that was converted from a tie-up using Convert to Lift Plan, it's possible that the conversion back to a tie-up may have the treadles in a different order.
