[Koha] join/merge some tag 952 to only one

[anabela semedo]

Hello people
I have multiple fields in my 952 file and would like to put them together so I can track the number of copies before importing them into the database.
for example I have:
952$a
952$b
952$y
952$9
and I wish it were like this:
952$a$b$y$9
but it's the only thing I can not do in the editmarc
Has anyone been through this yet and solved it?
