Is there a way to connect NASAC from Yggdrasil?

I am currently working on Yggdrasil with data from my NASAC.
I did not manage to find a simple way to transfer data transfer between NASAC and Yggdrasil. I was not able to mount NASAC from login1, so I transferred files in 2 steps. First from NASAC to my PC, then from my PC to Yggdrasil (and vice versa)

Is there a solution to simplify these data transfer ?
