That is it.
It will create one new material at a time.
The only way to add multiple surfaces at one time is with the Attribute Manager.
You will need access to a PLN file (or purposely save attribute file) that has different surfaces than you already have.
You can get these attributes from any PLN file that you can get your hands on.
I am not aware of any web resources where someone has saved a file specifically for surface materials.
You can create your own surfaces if you don’t want to use those in the catalogue.
Or use those an then modify them to your needs.
A word of warning.
If you are going to start creating new surfaces (or any other attributes come to that) you will need to be careful with the attribute index numbers.
You ideally want each attribute to have a different (unique) number to all the others and you want to keep these numbers the same across all of your files if you intend to copy and paste between files or use hotline modules.
Attribute management can get rather messy.
There are many posts in this forum on the subject.
