How to create a spring acting in two directions

Hello everyone.
I have a question about modeling in HyperMesh.
When I create a spring between two nodes, I want it to act in two directions.
In my traditional modeling, I created each of the two springs and assigned a separate PELAS property to each.
For working convenience, I would like to represent this with only one property.
I thought this functionality was in PBUSH, does it mean the same thing depending on the configuration?
Also, when I use BUSH for overlapping nodes, I often see the following error
CBUSH 0000 has zero length. (Note: not a shared node)
How can I create this?
Thanks for reading.
