How to add SMT test points ?

Hello ! 

I am trying to add SMT test points to a board but couldn't find a way to do that. I tried : 

• creating a single SMT pin footprint that I manually added, but I can't easily set a net to it to make it a test point.
• creating a SMT via (just a 0.6mm circle on bottom layer), but I cannot add them to the board. I can add them to the Via list in the Physical Constraints Manager, but when I try to add them by using the Cline command (like I would do to add a THT via), it doesn't work, the SMT via doesn't appear in the list...

How could I simply add an SMT via to the board ?

Thank you !
