Add shared connection with different group

Hello

I would like to know how to add servers in the shared connection, but group by a groupID.
I tried with a csv file with this format
"name","type","tags","groupId"
"server.domain.local","","","admin"

But apprently it doesn't work.

Of course if I try with a txt file and just a liste of servers it works, but I would like to groupe them by a groupID that I will indicated in the file.

Is it possible ?
