Unfortunately, I think the answer is no, it's not possible. I can't think of any way a *part* of a field can be copied over to a new field, I don't think HS can extract a single piece of the data.
But I am certainly going to stay tuned to see if anyone knows of a way this can be done!
I don't know of any way to split. I had to do a search, but there is a way to concatenate strings with HubL so if you captured the data in two fields it might be possible to join them into a field later that you could use. Or if you build out something custom via API you might be able to split out that way.
Maybe Zapier or Automate.io will allow splitting (or parsing at least). If so, you can pull the data out of HubSpot, split (or parse), then push the result back to a property in HubSpot.
Worth a look. Good luck.
