How to move one node to other group(group by comments)

Hi all,

As i am new to solarwinds, in my new company already solarwinds is running configured by our old staff.

now i am trying to learn about solarwinds, i got one small task.

all nodes are in different groups, that groups are defined as "group by comments"   now i want to move one node to another group,  see the below image in unknown[1], the node i want to move in Branches[37] group.

can any one  help me ? i checked the below

settings --> node management --> Manage groups..  but int that the group(group by comments) is not showing.

I hope anyone understand my question. Manythanks..
