New datum call without creating a new setup

[Stephen__Hall]

Bit of a strange ask this one....

A customer has used other CAM packages in the past with his 'quirky' machine and has had the ability to call up a tool and nominate a new datum but without having to create a new setup. He'd like to:

Create a setup with G54 >

Face mill the top  using G54>

Create a 2D Contour operation using G55 but without creating a new setup>

Revert back to G54 for the next tool/operation without creating another setup

Can anyone think of a workaround or can it not be done?

Found a workround:

Create setup>

Create face mill op.>

Setup tab > New Folder

Double-click the new folder > Post Process > Override WCS offset>

Create new op.>

Revert.
