Is there a way to import the new ratings into a created roster?

I made a roster when 2K had their previous rating update and I was wondering if there was a way to import the new ratings without having to redo the whole roster. I know that you can import a players attributes but it also imports the players signature shots and my entire roster was new signature shots so it doesn't help. I'd appreciate it if someone could let me know if there is a way to import the new ratings so I don't have to spend another week on a new roster. Thanks.

maybe you need to export player's dna from updated roster and then import them on your created roster.

yes use player dna

maybe you need to export player's dna from updated roster and then import them on your created roster.

That's what I was saying when I said that I know you can import the attributes but it also imports the signature shots and my created roster is fixed signature shots so it kinda defeats the purpose.
