No problem at all:

After the poses are as you want them:

1. Select the first figure's BODY

2. Select the "POSE" icon on the Poser Library pane. Open to where you see existing pose folders. Click the "+" sign that will appear at the bottom of the pane when it is open.

3.A box saying "New Set" will pop up. Enter the name you wish to give to this pose.

4. Click "Select Subset". This brings up a list of the items in the scene. Deselect (uncheck) everything that is NOT a part of the character pose you are wanting to save. Don't forget to uncheck "ground." Click OK.

5. Back at the New Set box, click "OK"

6. The next box asks about Morph Channels and Body Transformations. If all you want to save is the pose... the position the figure is in... leave these unchecked. If you want to save morph/scale changes, check them. Click OK.

7. Another box pops up marked "Save Frames." If it is a static pose, leave it selected to "Single Frame." If it is an animation sequence, click multi Frame. Click OK

 

An icon will appear in the Poser Library pane with the pose you selected. Repeat this for each character using a unique name for the pose.

To load these poses, simply select the desired character, then click the pose icon. It will automagically position your new figure as desired!
