Export a quilt only as a quilt (not surfaces) using STEP interface in Creo 4

Does anyone have experience exporting user selected quilt(s) to a step file? The workarounds I am aware of are rather cumbersome and I am looking for a streamlined method to use. Ideally I would like to be able to a select a quilt when exporting and have it sent as a quilt through the STEP interface.

The current documentation on the interface is severely lacking and has not been very helpful.

Assume the model has both solid a quilt geometry present.

The workarounds I have worked out to date:

1) Create two layers to isolate (via rules) solid geometry and quilts to prevent the solid geometry from exporting with the "As is" option in the STEP interface

2) Export quilts and solids as is and then use IDD to delete the solid geometry to leave the quilt behind when importing the STEP file

3) Export user selected quilt only as surfaces and stitch it together after import

#3 would work if the export was a quilt instead of individual surfaces.

Has anyone found a better method to do this?
